A rat has 42 chromosomes in eath somatic call. How many chromosomes are in each gamete

Answers

Answer 1

Answer:

21 chromosomes

Explanation:

Somatic cells are a diploid which have 2 sets of chromosomes. If two sets are 42 chromosomes, one set must be 21 chromosomes. Gametes are a haploid which have only 1 set of chromosomes. So in each gamete, there should be 21 chromosomes.

In your own words, what is a trophic cascade?

Answers

Answer:

A trophic cascade is a side-effect when a trophic level (species) of the ecosystem is reduced or removed. Their ecological species interactions keep entire ecosystems balanced. Hence, suppressing their numbers or changing their behavior due to predation risk, results in an ecological imbalance or a trophic cascade.

Explanation:

BRAINLIEST PLEASE ;)

Answer:

Tropic cascades in an eco-system is when a prey changes its behavior due to the predators attacks, thereby increasing in numbers indirectly for the survival of the predators.

A plant dies if it’s pholem tissue removed why

Answers

Question:-

A plant dies if it’s pholem tissue is removed. Why?

Answer:-

When the phloem is removed, no substance is transported, the plant does not have the necessary requirements to carry out the process (photosynthesis), and finally the plant dies.

Phloem is composed of various special cells called companion cells, phloem fibers, and phloem parenchyma cells.
Phloem helps the plant by carrying sugar,amino acids and other nutrients from roots to the leaves,stem and other parts of the plant. If the phloem is removed then the transportation of substances won't take place and plants would not get the needed requirements to carry out its process and at last the plant dies.

Yifei and Santos are making a diorama on the ecological role of organisms. Yifei wants to show the omnivores eating both plants and other animals, and the herbivores eating other animals. Santos wants to show the omnivores eating only other animals, and the herbivores eating both plants and animals. Who is right?

Answers

Answer:

None of them are correct because omnivores, from the root word "Omni" meaning "all", means omnivores eat both plants and animals. Then, herbivores only eat herbs, meaning plants, so both of them are wrong. Animals that eat other animals but not plants are called carnivores.

Summarize the lytic cycle. (1 point)

The viral DNA incorporates itself with the host cells and replicates whenever the host cell replicates itself.

A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.

A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.


A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.

Answers

Answer: A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell

The lytic cycle is one of the two main life cycles of viruses, the other being the lysogenic cycle. In the lytic cycle, a virus infects a host cell and hijacks its cellular machinery to replicate and produce new virus particles, or virions.

The correct option is D .

The lytic cycle is rapid and results in the destruction of the host cell. It is often associated with acute infections, where the symptoms of the infection are more severe and appear relatively quickly. Examples of viruses that follow the lytic cycle include the flu virus (influenza), the common cold virus (rhinovirus), and many bacteriophages that infect bacterial cells.

The lysogenic cycle, on the other hand, is characterized by the integration of the viral genetic material into the host cell's genome, allowing the virus to remain dormant for a period before switching to the lytic cycle.

Hence , D is the correct option

Be sure to explain how energy is processed and changed as it passes through and between each process.

EX: Stored energy in gas is converted to heat when you light the stove. This heat is transferred to the food as heat energy while it cooks.

Answers

The correct order of flow of energy and its conversion is

Light energyChemical energyPotential and Kinetic energy

During photosynthesis, plants converts light energy from the Sun into

chemical energy in the form of glucose. Cellular respiration involves the

conversion of chemical energy from glucose into potential and kinetic

energy by body cells

The chemical energy from glucose is converted into ATP which is another

form of chemical energy.The ATP formed helps cells perform various

activities and state of rest such as sleeping in the body through the

conversion of the chemical energy into kinetic and potential energy

respectively.

They are the fastest growing weed that allowed the plant to build huge populations in its ranges of introduction. They develop dense mats on the surface of the water and becoming a major weed problem.

due to their dense layering in  the surface the sun light cant travel properly in the water and the consumption of oxygen is also taken up by them hence it result the lack of oxygen in the water.
