Why does crab grass do so well when ordinary grass struggles in late summer? Is this a phenomenon ? Or is this based on a scientific principles, what is it that causes crab grass to thrive in relation to the different type of plants ?

Answers

Answer 1

Crab grass does so well when ordinary grass struggles in late summer

because its seed germination is higher when exposed to hotter

temperatures.

The seeds of crab grass are mostly dormant and their germination is

dependent on the soil temperature. During summer, the temperature of the

soil is usually higher which aids its growth .

This therefore explains the reason why crab grass does well than ordinary

grass in late summer periods.

Answers

Answer:

1. Glycolysis

2.false (not sure)

3. Cellular respiration is the process through which cells convert sugars into energy.

4 C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy)

5. Fermentation is a chemical process by which carbohydrates, such as starch and glucose, are broken down anaerobically.

6 anaerobic

7 alcoholic and lactic acid.

8 Alcoholic fermentation is a biotechnological process accomplished by yeast, some kinds of bacteria, or a few other microorganisms to convert sugars into ethyl alcohol and carbon dioxide. ... Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis.

9 In this reaction, a phosphate group (in red) is transferred from phosphocreatine to ADP to form ATP very rapidly, allowing muscle contraction to continue for about 10 seconds. When phosphocreatine is depleted, the muscles must turn to metabolism of fuel molecules to produce more ATP to power physical activity.

10 At this point, the runners' muscle cells are producing most of their ATP by lactic acid fermentation, which can usually supply enough ATP to last about 90 seconds.

12 After that, the body begins to break down other stored molecules, including fats, for energy. If photosynthesis is the process that "deposits" energy in a "savings account," then what is cellular respiration? It is the process that "withdraws" energy.

13 Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).

why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?

A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.​

Answers

Answer:

i think the answer should be b.

the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!

btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

a group of unicellular organisms that live together but have on relationship to one another

Answers

Colonial species are together

The group of unicellular organisms that live together but have no relation to one another is called colonial organisms.

What are colonial organisms?

The organization of cells leads to their efficiency. The organization of cells leads to the formation of tissues and organs which leads to the efficient functioning of an organism.

The organization of cells is not only seen in the multicellular level of organization. It starts from the organization of molecules to form structures like proteins and nucleic acid.

Unicellular organisms are able to live and survive independently and perform all life processes necessary for their own survival. But, bacteria are often found to live together in colonies.

A colony is a group of individual organisms that live close to each other. They live together because they are stronger in a colony. A colony of bacteria can protect themselves, acquire their nutrition or attack a host in a better way.

Therefore, a group of organisms who live close to each other and have no relationship is called colonial organisms.

What is the dominant allele?

The connection between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.

The Cross between parents is Bb x bb

Gametes- B and b

Offsprings- Bb, Bb, bb, bb

The crossing analysis is attached in the image below.

A person needs two copies of a recessive allele, one from each parent, in order for it to result in a recessive phenotype.

function of nucleus, mitochondria ,endoplasmic reticulum, vacuoles ​

Answers

Answer:

nucleus...controls all the activities of the cell and carrries the genes

mitochondria..site for respiration that yields energy for the cell

endoplasmic reticulum... protein synthesis and lipids metabolism

vacuoles.... handle waste products and are responsible for regulation of osmotic pressure of a cell also

Explanation:

is this helpful?

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.
