why do we study plants?​

Answers

Answer 1
Plants provide us with oxygen, food, fuel and fiber. Among other reasons, scientists study plants to improve and secure the food supply for an increasing world population, identify new sources of bioactive compounds and medicines, improve fiber production and identify sources of biofuels and biorenewable resources.

Answer:

1. Skull and crossbones

2. A triangle (commonly painted colour red or yellow) with an exclamation sign inside.

3. biohazard symbol

4. A radiation sign in the form of a triangle, having other little image descriptions inside.

Explanation:

Note that a biohazard material refers to dangerous substances of biological (living) nature that can pose a threat to humans. Thus, safety symbols try as much as to draw attention to the descriptions used.

For example, skull and crossbones and biohazard symbols are used to indicate that a material that is biohazard, such as bacteria could result in the death of a person.

Can someone describe these:
Menstrual Phase
Follicular Phase
and Luteal phase

Thanks!!!

Answers

Answer:

(menstrual phase) this is the phase where the unfertilized ovum and endometrium that was formed in readiness for implantation slough off or come out due to a sudden drop in progesterone levels

(follicular phase) this is where the graafian follicle in the ovary develops. from primary follicles due to secretion of follicle stimulating hormone by the pituitary gland and matures there after due LH hormone which will also stimulate the ovary to release the ovum

(luteal phase)this is the phase after the ovum has been released where the remains of the ruptured graafian follicle undergo reorganization to form a corpus luteum/yellow body which now produces progesterone which causes thickening of endometrium in readiness for implantation

hope this helps

Answer:

The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. 2) The follicular phase is a phase of the estrous cycle during which follicles in the ovary nature from primary to a fully mature grafian follicle.It ends with ovulation.3) The luteal phase begins during the second half of a menstrual cycle normally lasting around 12 14 days after the ovulation and it is responsible for producing progesterone.

O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin
was secreted after he ate the cookies because his blood glucose was high.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. Glucagon

O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he

O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he ate,
glucagon from the cookies increased his blood sugar levels.

Answers

Answer: Option A) Glucagon was secreted by his pancreas before he ate the cookies because blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.

Explanation:When Kai was hungry and his blood glucose level was decreasing, glucagon is the hormone which was secreted by the islets of pancreas to increase the blood sugar levels in his body. Glucagon forces the liver to release the stored glucose in it, which increases the blood glucose level in the body. When Kai ate the sugar cookies there was enough of blood glucose available for his body, also it exceeded the requirement and went high. Insulin was then secreted to control this excess glucose from the islets of pancreas. As it helps the body cells to absorb the glucose and lowers the amount of glucose in the blood. It makes the cell available with the glucose to produce energy and perform their activities.

In short, glucagon and insulin both are secreted by the same organ which is islets of pancreas. But they differ in their function, glucagon increases the blood glucose when the body needs it, whereas insulin helps to absorb the excessive glucose and stores that in the body. Both are the hormones which help in regulating the body glucose levels.

During  process of digestion which takes place in digestive tract statement which describes role of glucagon and insulin is glucagon was secreted by  pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate cookies because his blood glucose was high.

What is digestive tract?

It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.

The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

The temperate leaves are thin to minimize absorption of sunlight, while the taiga leaves are specialized to store water during the dry season. C. The temperate leaves shed water during the wet season, while the taiga leaves can enter long periods of dormancy during colder weather. D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing.

Answers

Answer:

The correct answer is option D.

Explanation:

The temperate leaves grow in temperate forests found in America, Europe, and Asia. This biome comprise of trees have evergreen conifers with needle like leaves. Such leaves can endure wide change of temperature and light. Some vegetation of temperate biome are conifers such as Pine, Hemlock and other. The trees shed their leaves with the beginning of fall and new leaves are delivered in late-winter  to protect from the cold.

On other hand, Taiga forest is the biggest biome on the planet. This biome contain conifers with long, slender waxy needles like leaves. These waxy leaves provide security against freezing temperature and from dying drying out. In contrast to temperate they don't sheds their leaves in winter and keep their needles throughout the entire year.

Explanation:

El cruzamiento entre un ejemplar homocigota dominante P (flores púrpura) y un homocigota recesivo p (flores blancas) para un rasgo determinado por un sólo un gen con dominancia completa producirá una generación filial F1 100% heterocigota. Por su parte, cuando cuando estos individuios cuyo genotipo es Pp se cruzan entre sí, los genotipos esperados en la F2 serán 1 (PP, homocigota dominante): 2 (Pp, heterocigota): 1 (pp, homocigota recesivo).

(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.

(c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell.

(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective permeability is property of living plasma membrane.

How does Photosynthesis relate to Cellular (aerobic) Respiration?
A. Photosynthesis breaks down glucose, Respiration builds it.
B. They are equal but opposite reactions.
C. Photosynthesis is for plants, while Respiration is for animals.
D. They are not related.

Answers

Answer: photosynthesis breaks down glucose. Hope you understand

Explanation:

Photosynthesis is related to Cellular (aerobic) Respiration in that they are equal but opposite reactions and the correct option is option B.

Photosynthesis and cellular respiration are complementary processes that are crucial for the energy flow in ecosystems. In photosynthesis, plants and some bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen. This process stores energy in the form of glucose.

In cellular respiration, organisms, including plants and animals, break down glucose and other organic molecules in the presence of oxygen to release energy for cellular activities. This process consumes glucose and oxygen and produces carbon dioxide and water as byproducts.

Photosynthesis and cellular respiration are interconnected through the exchange of products and reactants. The oxygen produced in photosynthesis is used in cellular respiration, while the carbon dioxide produced in cellular respiration is used in photosynthesis. As a result, they form a continuous cycle that maintains the balance of oxygen and carbon dioxide in the atmosphere and provides energy for living organisms.

Thus, the ideal selection is option B.
