contrast homozygous and heterozygous genotypes? Dont copy from the internet please
Answer:
I got you
Explanation:
homozygous is when the letters are AA or aa NOT Aa
heterozygous is when it is Aa
The homozygous can only pass down A or a, not both. If the parent was AA, the probability of their offspring would be more likely to have a dom. phenotype is more likely. If it was aa, they are more likel to create heterozygous and recessive offspring.
The heterozygous coding is able to pass on both the recessive and dom. traits. So the offspring would be more dependent on the other parent, but most likely will have more dom. offspring.

Food molecules such as proteins cannot be absorbed unless they are digested.
Give one reason why.
Answer:
Your body can't absorb proteins in their natural state. Certain proteases in your stomach and pancreas break the bonds that hold the amino acids in protein together so your body can absorb the composite amino acids individually.
Food molecules cannot be absorbed unless digested because ; They are too big to pass through the plasma membrane, in their natural state.
The food molecules such as protein needs to be broken down into its composites amino acids for easy absorption. food molecules, cannot be absorbed in their natural state because they are too big to pass through the plasma membrane.
Protein is broken down ( digested ) by proteases and pancreas into composite amino acids that is absorbable into the human cells.
Hence we can conclude that protein cannot be absorbed unless digested because they are too big to pass through the plasma membrane, in their natural state.

Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.
The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.
In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).

Answer: im not sure but i think it means to grow plant because it is talking the key words are to foster the growth of living things.
i hope it is right if not sorry!!!!!!!!!!!!!!!!!!!!!
Answer:
Aquaculture means to foster organisms (for the most part fish) that live in water.
Explanation:
After reading Holt Enviromental Science's Food and Agricultural Section: Animals and Agriculture passage, you can define aquaculture. In the passage it reads "fish farms generally consist of many individual ponds that each contain fish at a specific stage of development." The fish grow until they are matured and then "they are harvested."

Describe the sequence of events during a blood clot.
Answer: Hemostasis includes three steps that occur in a rapid sequence:
Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.
or:
The Blood Clotting Process
Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.
Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.
Platelet plug. ...

In a desert ecosystem, coyotes and rattlesnakes both eat the same type of mouse as a primary part of their diets. Recently, coyotes have been hunted and killed by people, decreasing the overall coyote population. How will this most likely affect the rattlesnake population over time?
Answer:
Answer: It will increase because coyotes are the competition.
Explanation:
An ecological niche can be defined as the functional role which an organism performs in the ecosystem in order to sustain it's life. The functional roles include how an organism obtains it's food, type of food eaten by the organism, type of habitat chosen by the organism and type of breeding season used by the organism.
In the given situation, both coyotes and rattlesnakes are dependent upon the same ecological niche that is they are dependent upon mouse as a primary part of their diets. As, both coyotes and rattlesnakes are dependent upon the same diet there may exist the competition between the two species. But it is mentioned that the coyote population is decreasing therefore the population of rattlesnake will most likely increase as the competition for the same diet decreased.

Your friend has a dog with fleas. She goes to the pet store and buys over-the-counter flea medicine. It does not work. So she goes to the veterinarian and explains that she just spent $80 on medicine that does not work. The vet casually says, “Oh yeah, that medicine does not work anymore.” Because you now understand natural selection, your friend asks you questions. Answer them with evidence.
- What do the resistant fleas do that the sensitive fleas do not?
Answer:
Explanation:
The dog has fleas, but the medicine to counter this does not work. This means that the fleas have built up a resistance against the drug to ensure continued survival and reproductive success of these organisms. These resistant fleas may have existed in population as the population is always large but in small amounts. Thus, treatment with the drug will lead to the dieing out of the sensitive fleas and then leaving the resistant fleas with the favourable alleles to be selected for.
These favourable traits that have evolved against the drugs are then selected for and the organisms reproduce giving rise to more fleas with these favourable characteristics (being resistant to the drugs) such that their continued survival and reproductive is ensured compared to the sensitive fleas that die out.

Crossing-over can happen at any location on homologous chromosomes. The farther apart two genes are, the more likely that crossing-over would separate them.
On these chromosomes, which pair of genes would be most likely to be separated by crossing-over: A and B, or A and C? Why?
Answer:
The answer is C I believe. Chromosomes usually make a pattern and thats the points were it would make a pattern.
~Paige~Crossing-over chromosomes.
The crossing of the chromosomes is the swap or the exchange of genetic materials. It takes place in the germline, at the formation of the egg. This is also called meiosis. It aligns with DNA sequencing. The pried chromosomes cross over the other.
Thus the answer is they make a pattern that points in the pattern.
This shows the crossing happens at the homologous chromosome. The farthest apart two genes the most likely they cross each other that would separate them. Thus the option C is correct. They cross at the end., hence is a process called recombination.Learn more about the chromosomes.

What events occur during high tide
Answer:
The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. As the Earth rotates, your region of Earth passes through both of these bulges each day. When you're in one of the bulges, you experience a high tide.

What are the weaknesses or inaccuracies in the model the student created?
Answer:
The model appears to show the carbon dioxide molecules entering the blood cell and the oxygen molecules existing the cell.
Answer:
Explanation:
The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.
