Chemicals used in chemotherapy treatments to fight cancer can also harm cells in hair follicles and bone marrow.
What characteristic do these cels most likely share with cancerous cells?
O They form tumors.
O They spread through the blood.
• They divide rapidly.
O They contain a mutation.
A

Answers

Answer:

They divide rapidly

Explanation:

Some normal cells such as hair follicles cells, mouth cells, digestive tract cells, and bone marrow cells divide rapidly. In mammalians, hair follicle cells are cells localized in the skin, specifically in the dermal layer of the skin. In this region, epidermal cells that form the root of the hair divide rapidly by interacting with neuropeptides, hormones, and immune cells. On the other hand, the bone marrow is a spongy tissue found in bones that contain stem cells (which also divide rapidly). In consequence, it is well-known that high-dose chemotherapy treatments may damage these types of cells.

The food of come from autotrophic plant to animal through food chain. The energy cycles between the air and soil and plants, animals, and microbes occur by food web.

What are the components of food web?

A food web is defined as the cyclical event of energy transfer among different trophic level of organism.

The major components are primary producers, primary consumers, secondary consumers, tertiary consumers, quaternary consumers

Primary producers are the green autotrophic plants and capture some of the solar energy  and convert it into chemical energy by photosynthesis.

The net primary productivity (NPP) of energy is defined as the rate of photosynthesis minus the rate of respiration of plants.

Primary consumers or herbivores feed on producers constitute  the second trophic level of the food web.

in third tropic level, Secondary consumers eat primary consumers where as  tertiary consumers, quaternary consumers or predators, carnivores or omnivores, which are both plant- and animal-eaters, such as humans.

1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.

Answers

Answer:

1. Stamen and pistil

2. Pollen, microspore

Explanation:

The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).

The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).

You are looking at the side of a cliff with many horizontal rock layers. In the upper layers you find fossils of rodents, but in layers further below you find amphibians but no rodents. In some still-deeper layers there are neither amphibians nor rodents but there are fossils of beetles and other insects. In the deepest layers you find no insects but you do find millipedes. This fossil evidence suggests that

Answers

Answer:

millipedes were the first of these animal groups to evolve.

Explanation:

Fossils are structural remains of animals from the past. As these animals die, it takes years for the remains to be buried.

The millipedes are at the lower layer of the rock, next to insects, amphibians, and then rodents. This shows that millipedes existed and evolved before the rest of the found animal fossils.

Use evidence from the text in your response.The rise in popularity of farmers' markets has caused many people to rethink their use of regular grocery stores. Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store. All in all, the freshness and quality of food is worth a little more money. Farmers' markets are the way to go. Thanks!!
