6. Two different populations of similar organisms are considered separate species when they are _____ isolated.

Answers

When two populations of similar organisms are reproductively isolated, then we consider them as separate species.

Species are formed when there is reproductive isolation between the different populations of similar organisms. Reproductive isolation can happen due to several factors such as environmental problems and natural calamities. Sometimes, a barrier arises between the two populations due to which populations of similar organisms get separated and the individuals of each population reproduce within their population. With time, their genetic makeup changes and they become separate species. The two species can have many similar characteristics. But, they will have genetic variations. For example- Solanum tuberosum and Solanum melongena are two different species but they have some common characteristics.

Thus, when no reproduction occurs between the two populations from similar organisms, then they become different species.

____________________ are structures inside cells that perform specific functions and are often enclosed in membranes; these can be seen with an electron microscope. Your answer:

Answers

Answer:

Organelles

Explanation:

Living cells of organisms contain structures within them that perform specific functions for the cell. These structures are called ORGANELLES. Organelles are organ-like structures that are specific about their function in a cell.

Both the cells of prokaryotes and eukaryotes possess organelles, however, the organelles in eukaryotes are bounded by a membrane e.g mitochondrion, chloroplast etc. while those of prokaryotic cells are not bounded by a membrane.

The organelles inside a cell can be seen with the aid of an electron microscope. Examples of organelles are chloroplast (functions in photosynthesis), mitochondria (functions in production and storage of cellular energy), ribosome (functions in protein synthesis) etc.

What is Leonardo da Vinci's best work

Answers

Answer:

Leonardo da Vinci: Mona Lisa

Explanation:

The world's most famous artwork, the Mona Lisa draws thousands of visitors to the Louvre Museum each day, many of whom are compelled by the sitter's mysterious gaze and enigmatic smile.

The world’s most famous artwork, the Mona Lisa draws thousands of visitors to the Louvre Museum each day, many of whom are compelled by the sitter’s mysterious gaze and enigmatic smile. The seemingly ordinary portrait of a young woman dressed modestly in a thin veil, somber colors, and no jewelry might also confound its viewers, who may wonder what all the fuss is about.

The painting’s simplicity belies Leonardo’s talent for realism. The subject’s softly modeled face shows his skillful handling of sfumato, an artistic technique that uses subtle gradations of light and shadow, rather than line, to model form. The delicately painted veil, the finely wrought tresses, and the careful rendering of folded fabric reveal Leonardo’s tireless patience in recreating his studied observations. Moreover, the sitter’s perplexing expression only adds to her realism. Her smile might be engaging or it might be mocking—viewers can’t quite figure it out because, like a human, she is a complex figure, embodying contrary characteristics simultaneously.

Theoretically, if several individuals who score high on a test have a substantial number of low responses, and individuals who score low on the test have a substantial number of high responses, then the test is likely to have which of the following?   a. High validity  b. Low validity  c. High reliability  d. Low reliability

Answers

If several individuals who score high on a test have a substantial number of low responses, and individuals who score low on the test have a substantial number of high responses, then the test is likely to have Low validity. The correct answer is B.

Validity refers to the accuracy or truthfulness of a test, or whether it measures what it is supposed to measure. If individuals who score high on a test have a substantial number of low responses and individuals who score low on the test have a substantial number of high responses, this suggests that the test is not accurately measuring the characteristic or construct it is intended to measure. This would indicate low validity.

Reliability, on the other hand, refers to the consistency or stability of a test. A test can have high reliability and still have low validity if it consistently measures the wrong thing.

Fruit flies with one allele for curly wings (Cy) and one allele for normal wings (Cy ) have curly wings. When two curly-winged flies were crossed, 203 curly-winged and 98 normal-winged flies were obtained. In fact, all crosses between curly-winged flies produce nearly the same curly : normal ratio among the progeny. If a curly-winged fly was mated to a normal-winged fly, how many curly-winged flies would you expect among 270 total offspring

Answers

If there are 270 total offspring, we would expect

135 curly-winged flies

As flies with one curly allele (Cy) & one normal allele (Cy+) have curly wing, curly wing is dominant to normal wing.

Two curly-winged flies produce 203 curly-winged & 98 normal-winged flies. This is almost in 2:1 ratio for curly wings: normal wings. But expected ratio in offspring when two heterozygous flies are crossed is 3:1.

Only possibility is that homo-zygous for curly gene is lethal, i.e., CyCy genotype is lethal. So, if a curly-winged fly is survived its genotype will be Cy Cy+. Genotype of normal-winged fly will be Cy+ Cy+

The cross between one curly-winged & one normal-winged fly is shown in below Punnett square.

Gametes                     Cy+                              Cy+

Cy               Cy Cy+ (Curly wing)               Cy Cy+ (Curly wing)

Cy+             Cy+ Cy+ (Normal wing)      Cy+ Cy+ (Normal wing)

We find that expected ratio for curly & normal-winged fly is 1:1. Thus, among 270 offspring we will expect \(\frac{270}{2}\) = 135 offspring of curly-winged.

as a pelican flies above the water's surface why must it aim for the fish in slightly different place than fish appears to be located

Answers

The reason it must aim for the fish in a slightly different place than where the fish appears to be located is option D: Light waves are refracted as they travel from air to water.

What is the refraction about?

Light slows down when it transitions from less dense air into more dense glass or water. The light ray changes direction as a result of the slowing of the light. Refraction is brought on by a change in the light's speed.

We know that when light tends to bends away from the normal when it reaches the air, which is why the pelican must dive in front of the horizontally oriented image of the fish because of the law of refraction.

So, The angle at which the light exits the water from the fish bends it away from the normal, giving the impression that the fish is closer to the surface.

A pelican hunts fish in the water. As the pelican flies above the water’s surface, why must it aim for the fish in a slightly different place than where the fish appears to be located?

answer choices

Light reflects off the fish, except for light of the wavelength the fish absorbs, making the fish hard to see.

Water absorbs most of the light, so not much light reaches the pelican’s eyes.

Energy from the ocean waves is transferred to the light waves.

When you push down on a block resting on a table, block atoms and table atoms that are in contact with one another.

Answers

When you push down on a block resting on a table, the atoms of the block and the atoms of the table that are in contact with each other and get  interact through intermolecular forces.

In general , forces that include van der Waals forces, hydrogen bonding, will helps the atoms to repel from each other. Hence, When you push down upon a block, you are applying an external force to it , that will cause the atoms at the surface of the block to compress slightly.

The compression will then results to an increase in the contact force between the block and the table, that as a result will  prevents the block from moving downward further. Hence , the force lying between the atoms at the surface of the block and the force at the atoms in table get balanced, and the block remains stationary.

if the ecosystem is a closed system do you think the total amount of matter in an ecosystem changes?

Answers

Any ecosystem is an example that describes the open ecosystem, if the ecosystem is a closed system, it exchanges energy but does not matter.

What happens to matter in the closed ecosystem?

Based on the movement of total matter into or outside the entire system, ecosystems can be divided into two general categories: open and closed. Closed systems exchange only energy, not matter, and are incredibly self-contained.

Physical and chemical changes can cause matter to change into different forms, but no matter what happens, the matter is always conserved.

Therefore, there is no creation or destruction of matter; the amount of matter is the same before and after the change.

Answers

Placebo is something used in experiments to proove that a drug for example is effective. In these experiments several people are summoned, a group receives the drug in question and the other group the placebo that is a substance (or the inactive drug) with no positive or negative effect on health. The participants in the clinical trial don’t know if they receive the real thing or the placebo. Researchers can measure if the drug works by comparing how both groups react. In this way the effectiveness of the drug is tested in comparison with the placebo.

Sometimes a person can have a response to a placebo and so the placebo effect occurs. For instance the person may have what appears to be side effects from the treatment (positive effect). Your mind can be a powerful healing tool when given the chance, your brain can convince your body a fake treatment is the real thing. Some people can experiment a negative effect and symptoms may improve.

Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer

Answers

Answer:

The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.

Q3: Classify the parasites that cause human disease; give an example for each one
.and Mention the name of disease, location in host, and the mode
transmission of these parasites .

Answers

Parasites that cause human disease can be classified into different groups based on their characteristics and the diseases they cause. Here are some examples:

1. Protozoa:

  - Example: Plasmodium falciparum

  - Disease: Malaria

  - Location in Host: Plasmodium parasites reside and multiply within red blood cells.

  - Mode of Transmission: Mosquitoes (Anopheles species) transmit the parasite to humans through their bites.

2. Helminths (Worms):

  - Example: Ascaris lumbricoides

  - Disease: Ascariasis

  - Location in Host: Adult worms reside in the small intestine.

  - Mode of Transmission: Ingestion of eggs present in contaminated food, water, or soil.

3. Nematodes (Roundworms):

  - Example: Enterobius vermicularis

  - Disease: Enterobiasis (Pinworm infection)

  - Location in Host: Adult worms inhabit the large intestine, while females migrate to the perianal area to lay eggs.

  - Mode of Transmission: Ingestion of infective eggs, which are usually transferred from contaminated surfaces or through direct contact with an infected person.

4. Trematodes (Flukes):

  - Example: Schistosoma mansoni

  - Disease: Schistosomiasis (Bilharzia)

  - Location in Host: Adult worms reside in the blood vessels surrounding the intestines and liver.

  - Mode of Transmission: Contact with water bodies infested with freshwater snails that release the parasite larvae, which can penetrate the skin of humans.

5. Cestodes (Tapeworms):

  - Example: Taenia solium

  - Disease: Taeniasis (Tapeworm infection)

  - Location in Host: Adult worms reside in the human intestine, where they attach to the intestinal wall.

  - Mode of Transmission: Consumption of undercooked or raw contaminated meat containing the larvae or ingestion of food or water contaminated with eggs.

It's important to note that this list provides only a few examples, and there are numerous other parasites that can cause diseases in humans. The diseases mentioned here represent a fraction of the many parasitic infections that can occur, and each parasite has its unique characteristics, geographical distribution, and mode of transmission. Proper diagnosis, treatment, and preventive measures are essential for managing these parasitic infections.
