Explanation:

Forests occupy the most favourable environments, where moisture is adequate for growth and survival of a tall, dense vegetation dominated by trees. Deserts are found where moisture is so lacking that a continuous, permanent vegetation cover cannot be maintained. Grasslands lie between these two extremes

Explanation:

Desserts: A desolate terrain, especially one with little water or vegetation; a wasteland.

Grassland: An area dominated by grass or grasslike vegetation.

Forest: A dense collection of trees covering a relatively large area. Larger than woods.

Answer:Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing. If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected.Measles is caused by a virus in the paramyxovirus family and it is normally passed through direct contact and through the air. The virus infects the respiratory tract, then spreads throughout the body. Measles is a human disease and is not known to occur in animals.

It usually begins as flat red spots that appear on the face at the hairline and spread downward to the neck, trunk, arms, legs, and feet. Small raised bumps may also appear on top of the flat red spots. The spots may become joined together as they spread from the head to the rest of the body.

Explanation:

Bear can live on land in a very cold regions of earth with the help of its thick skin and more hair on its body.

Frogs lives on lands due to its body structure and food availability. It has sticky tongue that captures insects.

Humans lives on lands not in water due to its body structure because its body structure can't allow humans to live in water due to absence of gills.

Seagull lives in the aquatic ecosystem because seagull feeds on fishes and other marine animals.

Sharks lives in water due to its body structure such as gills that are used to respire in water and the shark can't respire without water.

Meerkat lives in the arid climate because they lives underground to save themselves from the environment and the presence of food.

Protea lives in desert due to their dry skin that can tolerate the warm temperature.

Lions lives in the jungle due to the presence of food such as deer, buffalo etc and warm environment.

Dragonfly lives on land and water due to feed on the larva of mosquitoes that is present in the water bodies and good environmental conditions.

Answer:

The palisade layer  

Explanation:

The palisade mesophyll layer of the leaves is a layer of columnar cells that contain many chloroplasts. This layer is localized right below the epidermis and cuticle of a leaf. The chloroplasts localized in this layer contain chlorophyll, which is the green pigment used to absorb light in order to carry out photosynthesis.

Answer:

3 long whiskers: 1 short whiskers

Explanation:

This question involves a single gene coding for whiskers length in a certain animal. The allele for long whiskers (W) is dominant over the allele for short whiskers (w). This means that a heterozygous individual (Ww) will possess a long whisker.

According to this question, a heterozygous female with long whiskers (Ww) mates with a heterozygous male with long whiskers (Ww). The proportion of offsprings that will be produced from this cross (see punnet square) is as follows:

WW, Ww, Ww, ww

WW, Ww, Ww offsprings will possess a long whisker while 'ww' offspring will possess a short whisker. Hence, the phenotypic ratio will be 3 long whiskers: 1 short whiskers

Answer:

C. Cutting down forests.

Explanation:

Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.

The effects of an increase in CO2 concentration in the atmosphere is as follows:

- increase in water contamination and floods

- ocean acidification

- reduction of cold-related deaths

However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.

The correct way to accomplish this task is that the student needs to clone a transit sequence into the gene for hexokinase into these cells.

Explanation:

Clone is a hereditarily indistinguishable duplicate of a living being. It could be normally happening or made in the lab. There are various sorts of cloning systems; the most ordinarily utilized strategy is rDNA innovation and technology. During the cycle of rDNA innovation, unfamiliar DNA particles brought into target cells through the vector ( for example Plasmid). This technique is most generally utilized in gene transfer methodologies and gene articulations studies.

So, from the experiment; The correct way to accomplish this task is that the student needs to clone a transit sequence into the gene for hexokinase into these cells.

Answer: Helper T cells, or Th cells, coordinate immune responses by communicating with other cells. In most cases, T cells only recognize an antigen if it is carried on the surface of a cell by one of the body's own MHC, or major histocompatibility complex, molecules.

Explanation:

Answer:

T cells identify pathogens based on antigens on the surface of pathogens. The T cells then multiply and stimulate B cells to produce antibodies. The antibodies attach to the antigens, making the pathogens a target for phagocytes.

Answer: A. By selecting dominant genotypes

Explanation:

Artificial selection or selective breeding can be defined as the induced breeding process in which humans select parents of plants and animals that have desired traits that are beneficial for them to produce offspring that have characteristics of both parents and they are of improved yield and quality. This brings the change in the phenotypes of the offspring as compared to the parents. As the passage of dominant desirable traits in the genotype from either of the parent when gets expressed then the phenotype of the organism also change.

Spiders can regrow missing legs or parts of legs.

Sponges can be divided

Answer Starfish

These five-limbed creatures can regrow arms that detach from their central disc, and some species have even been observed to complete the process in reverse: regrowing an entire body from a lost arm. To do this the starfish will store nutrients in the arm until it is able to regrow its

Mexican tetra

Researchers in Mexico last week described how they are studying cave-dwelling tetra fish to better understand why some animals can regenerate tissue but others can’t. The scientists performed surgery to remove some of the heart of river fish and cave fish from the species Astyanax mexicanus, finding that while some river fish do regenerate tissue, the cave fish just grew scars over the damage.

Salamander

The amphibious salamander can regrow a lost tail to full length. This process sees cells migrating to the wound and then slowly regenerating the tail within a few weeks. The finished appendage is completely functional and has all the features of the original, with the spinal cord and nerves growing back too.

Axolotl

A relative of the salamander but even more skilled at regenerating is the axolotl. This animal can regenerate not just its tail but also limbs, skin and almost any other body part. Researchers found that each time a limb was removed, it regrew almost perfectly. The pale pink creature has since become the focus of research into human limb regeneration.

Answer:

The water vascular system of echinoderms (B) functions in locomotion and feeding.

Which of the following combinations of phylum and description is correct?   (C) Platyhelminthes—flatworms, gastrovascular cavity, no body cavity

Explanation:

Echinoderms are marine animals. They have a water vascular system that make them able to move (locomation), respiration and food and waste transportation. This system is full of different canal along the body.  

Echinodermata has not a radial symmetry as a larva, in fact it has a bilateral symmetry and coelom present. When it comes to Nematoda, they are roundworms and have a pseudocoelomate. Finally, porifera has a gastrovascular cavity and no coelom.

Explanation:

We can classify living things on these things:-

1) If they can carry out processes like respiration, ingestion.

2) If they move on their own

3) if they can talk

THIS WAS A FAIRLY SIMPLE QUESTION!

Yeasts change from mitotic to meiotic division when conditions are unfavorable because meiosis increases genetic diversity and improves their chances of survival in unfavorable conditions.

During meiosis, crossing over of genetic materials between non-homologous chromosomes creates genetic recombination and makes the resulting offspring to be genetically more diverse than their parents.

The increased genetic diversity will increase the chances of survival of the offspring in a constantly changing environment. In other words, the more genetically diverse a population is, the more their chances of surviving adverse environmental conditions.
