how the body's white blood cells respond to infections.

Answers

Answer 1
If a pathogen enters your body, white blood cells of your immune system quickly recognise its foreign antigens. This stimulates specific lymphocytes to grow, multiply and finally produce antibodies that will stick to the antigens on the invading pathogens and destroy them.

3.) bbSs
4.)Bbss

Answers

Answer:

bbss

Explanation:

mitochondria is the powerhouse of a cell

The genotype for the organism is represented by box 2 - 1.) bbss.

Punnett square is a way to find the genotype of any trait either monohybrid or more than one allele. To predict the outcome of breeding experiments where one trait with two boxes and two traits are being followed and the Punnett square is larger, with sixteen boxes.

Each side has gametes, representing alleles they have, produced by each parent.Each box shows the zygote that has a genotype combination of the gametes.for instance, here bs is fused with bs which form the zygote that contains the genotype bsbs.

Thus, The genotype for the organism is represented by box 2 - 1.) bbss.

How do I write a essay using the digestive urinary and excretory system to maintain homeostasis.

Answers

Homeostasis is balance. The shortest answer to your essay is that these 3 systems remove toxins from the body. Some of these toxins are in the air & food we take in, and some are just waste products after we process food.

The digestive system takes the food we eat, pulls out the energy we need to move and live, and passes on the waste to be excreted. If it didn’t excrete the waste, toxins would build up in the body.

The urinary system maintains homeostasis by filtering toxins out of the blood, and deciding how much water should be retained or wasted, based on our blood’s chemistry.

Another part of the excretory system is our skin. We sweat out toxins from exercise.

I hope these ideas are helpful to get to through your essay.

What is a phylum?

A taxonomic hierarchy is a system used to classify and organize living organisms based on their shared characteristics and evolutionary relationships, and the hierarchy is composed of different levels or ranks, and at the top is the domain, which represents the broadest and most inclusive category, while below the domain are the kingdoms, followed by phyla, classes, orders, families, etc. Phyla are one of the broader categories in the hierarchy, and they include groups of organisms with a common ancestor and shared characteristics that distinguish them from other groups, and an examples of phyla include the chordata.

How would the way I dress be impacted if photosynthesis stopped tomorrow?

thank you you're a lifesaver

Answers

Answer:

i dont want to do so much writing but i guess i will help

Explanation:

If photosynthesis came to an abrupt end, most plants would die within short order. Although they could hold out for a few days -- or in some cases, a few weeks -- how long they lived would largely be a factor of how much sugar they had stored within their cells. Large trees, for example, may be able to soldier on for several years — perhaps even a few decades — because of their energy stores and the slow rate of use. However, the majority of plants would meet a withering end, and so would the animals that rely on them for nourishment. With all the herbivores dead, the omnivores and carnivores would soon follow. Although these meat-eaters could feed on all the carcasses strewn about, that supply wouldn't last more than a few days. Then the animals that temporarily relied on them for sustenance would die.

What are the new cells called and how do they compare with each other?

Answers

Answer:

The original cell is called the mother cell and the two new cells are called daughter cells.

Explanation:

The mitotic (M) phase and cytokinesis (C phase) together are called cell division, the division of the parent cell (original) into two daughter cells (new cells), each with the same genetic information (chromosomes) as the parent cell. Mitosis does NOT occur in prokaryotic cells that do NOT have a nucleus. (tesd. net)

The nucleus divides during mitosis, while the cytoplasm divides during cytokinesis. The two new cells are referred to as daughter cells.

What is daughter cells?Diploid cells are the daughter cells of mitosis. Diploid cells have two complete chromosome sets. Mitosis creates no genetic diversity in normal healthy cells because the daughter cells have exact copies of their parent cell's DNA. Either of the two cells formed when a cell divides through mitosis. Because they have the same number and type of chromosomes as the parent cell, daughter cells are genetically identical. Daughter cells are formed by the division of a single parent cell. They are produced by the mitotic and meiotic division processes. Cell division is the reproductive mechanism that allows living organisms to grow, develop, and reproduce.

A food web is the representation which consists of all the food chains in a single ecosystem. Each living thing in an ecosystem has the part of multiple food chains. Each food chain in the ecosystem is one possible path which the energy and nutrients may take as they move through the different ecosystems.

The food web shows more of the interactions which are present between organisms of the ecosystem and the trophic levels which are included from the different trophic levels such as producers to consumers to decomposers. In a food web, an organism have a choice of what to eat.
