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.

Black fur colour is controlled by a dominant allele, B, and brown fur color by it's recessive allele, b. This characteristic is NOT sex linked. Give the genotypes of the parents and offspring of a cross between a black male and a brown female that produces 1/2 black offspring and 1/2 brown offspring.
Show all steps in working of this problem.
Answer:
What are specialized cells
Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.
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.
Therefore, Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.

what is cellular respiration?

14. How are photosynthesis and cellular respiration opposite in terms of oxygen?
produces less energy than aerobic respiration.
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).

1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. Type your answer here:
Explanation:
The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.

explain the effect of germination on pea seed respiration
Answer:
"The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration."

Where is the rainshadow area on the Big Island of Hawaii? Please help
Answer:
Applied to the Big Island, since the trade winds blow from the northeast and must pass over the mass of Mauna Kea and Mauna Loa, it means that the Hilo side is considerably rainier than the Kona side. The best place to view this rain shadow effect is to drive from Kohala to Hilo through the town of Waimea.

Explanation:
Why is air temperature above land warmer than the air temperature above water in the same location during the summer?
Answer:
Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water
Explanation:
Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.

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

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.
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!
