Explain how humans are able to produce one type of hemoglobin as they develop in utero, then produce another to use after birth
Answer:
Hemoglobin F has a different composition from the adult forms of hemoglobin, which allows it to bind (or attach to) oxygen more strongly. This way, the developing fetus is able to retrieve oxygen from the mother's bloodstream, which occurs through the placenta found in the mother's uterus.

what is the movement that helps the movement of undigested food through the large intestine?
Answer:
Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.

Describe the Lytic cycle.
No dam links
Answer:
Ok here ya go
Explanation:
The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane. Now during the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages.

what is chemical weathering? what are some facts?
Answer:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Explanation:
1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.

(PLEASE HELP!!!) Suppose scientists genetically modified a species of algae to produce more oil. This algal species reproduces asexually. Will all of the offspring of the genetically-modified algae also produce more oil? How do you know?
Answer:
Yes all of the offspring of the genetically-modified algae would produce more oil.
Explanation:
When an organism is genetically-modified to reproduce asexually, it makes exact copies of itself since it is the only one passing genes whereas if normal sex were to occur and both parents would pass 50%-50% of their genes down to the child.

Why are organisms in lower parts of the food chain not affected but organisms at the top of the food chain are?
Answer:
the organisms at the top of the food chain are effected because theyre bigger and the need more food and prey to survive. for example sharks, if fish arent thriving because they arent eating enough from the bottom of the food chain, the sharks cant eat them and the sharks will starve.
Explanation:
Answer:
The organisms at the bottom of the food chain have a tendency of reproducing faster. (unlike the top of the food chain). Don't think that the the organisms at the bottom of the food chain are not as important though! Everything is important in any food chain!

The 4 kingdoms of living things
one common ancestor
Answer:
one common ancestor
Explanation:
Although Darwin’s theory is often described as the theory of evolution by natural selection, most commentators recognize that common ancestry (the idea that all organisms now alive on earth and all present day fossils trace back to one or a few “original progenitors”) is an important part of the Darwinian picture.
Answer:
Darwin explained that all life came from one common ancestor.

Answer:
Please find the mRNA and amino acid of the DNA sequence in the table below.
Explanation:
This question is describing the processes of transcription and translation. Transcription is the synthesis of mRNA from a DNA template while translation is the synthesis of an amino acid sequence from a mRNA sequence.
The following nucleotides combination are given in this question. Their transcription into mRNA using the complementary base pairing rule is as follows;
DNA = mRNA
- ATG = UAC
- GTA = CAU
- CAA = GUU
- AAT = UUA
- GCG = CGC
- TGT = ACA
- ACT = UGA
- CCC = GGG
- TAG = AUC
Using the codon chart attached as an image, the translation of these mRNA codons is as follows:
mRNA = amino acid
- UAC = tyrosine (tyr)
- CAU = histidine (his)
- GUU = Valine (Val)
- UUA = Leucine (leu)
- CGC = Arginine (Arg)
- ACA = threonine (Thr)
- UGA = STOP codon
- GGG = Valine (Val)
- AUC = Isoleucine (Iso)
Question 5 (5 points) (04.03 MC) A student made the following diagram to represent cellular respiration. Why is this diagram incorrect?
A.water is not used up during this process.
B.glucose is not used up during this process.
C. The arrow for oxygen should point in the opposite direction.
D. the arrow for carbon dioxide should point in the opposite direction.
Answer:
A
Explanation:
The chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O (+ ATP)OR: Glucose + Oxygen → Carbon Dioxide + Water (+ Energy)
Since water is on the right side of this equation, it is produced as a result of the metabolic process rather than used up. So, the correct is A.

As a result of the experiment scientists did with Mexican tetras, it seems likely that their first hypothesis about blindness in the tetras is right. Explain how the result of the experiment supports their first hypothesis.
The scientists' first hypothesis is that blindness gives the fish some sort of evolutionary advantage, but not directly.
The experiment was: The scientists transplanted a lens from the eye of a surface tetra embryo into the eye of a cave tetra embryo. The result was striking—the surface tetra lens into the cave tetra caused all of the surrounding tissues to develop into a healthy eye.
A result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.
What is a hypothesis?An scientific hypothesis is a given explanation to a scientific observation from the real world.
A hypothesis must be verifiable, which means that it can be confirmed or rejected by using the scientific method.
In conclusion, a result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.

Explanation:
Stomach flu—or gastroenteritis—is an infection of the stomach and upper part of the small intestine. Common symptoms are diarrhea, vomiting, stomach pain, and cramps. Rotavirus and norovirus, which affect millions of people every year, are often the cause. Gastroenteritis often clears up on its own, but you lose fluids through diarrhea and vomiting. Prevent dehydration by drinking water and electrolyte drinks.
Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
a. They would have half chromosomes as much as the plants body cells.
b. Meiosis
Explanation:
Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.
Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.
In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.
