phosphate from atp is removed to make adp and a free phosphate molecule
Answer:
ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. ... When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
How does the natural process of meiosis support evolution?
Answer:
During meiosis the step of crossing over is the major source of bringing evolution.
Explanation:
Hitchhiker's thumb is inherited via two recessive alleles and causes a hyperextensibility of the thumb. The dominant allele causes a straight thumb phenotype. Predict the phenotypic and genotypic ratios from the following cross.
One parent with Hitchhiker's thumb crossed with a Straight thumbed individual who had a parent with Hitchhiker's thumb.
a. Phenotypic and Genotypic 1:1
b. Phenotypic 2:1 and Genotypic 1:1
c. Phenotypic 1:1 and Genotypic 2:1
d. Phenotypic and Genotypic 3:1
Answer:
a. Phenotypic and Genotypic 1:1
Explanation:
Two recessive alleles are required in order to be phenotypically affected for Hitchhiker's thumb. Hence, the genotype of the parent with Hitchhiker's thumb would be homozygous recessive.
Assuming the trait to be represented by the allele h, the genotype of the parent with Hitchhiker's thumb would be hh while the genotype of an individual with straight thumb who had a parent with Hitchhiker's thumb would be heterozygous, Hh.
Crossing the two individuals.
hh x Hh
Progeny: Hh hh Hh hh
Hh - Straight thumb
hh - Hitchhiker's thumb
Hence, the genotypic ratio is 1:1 while the phenotypic ratio is also 1:1.
The correct option is a.

Cells must maintain an appropriate level of fluidity across their membranes. Hot temperatures lead to greater membrane fluidity. What might you then expect to find regarding the membrane composition of bacteria from very hot environments
Answer:
Thermophilic bacterial are rich in large quantity of thermophilic lipids in the cell membranes. This components made the membrane to be impermeable at high temperature, and therefore a good adaptation for the hot environment.
At high temperature,proton permeability increase, sodium permeability also increases but to a ;lesser extent, but Lipid is independent of this temperature rise.
Hence, these organisms rely on the less permeable Na+ for the maintenance of high sodium motive force.it is the energy derived from this that the cell membrane needs to maintain stability, coupe with the lipid content.

g B. PROTEINS 1. Name the gastric enzyme that initiates protein digestion. Explain how this enzyme is activated. Pepsin is the gastric enzyme that initiates protein digestion. It is activated by stomach acid into the active form. It then breaks down the protein in our food into smaller particles like peptide fragments and amino acids. 2. Name the ducts in the pathway by which pancreatic juice flows from the pancreas to the duodenum. The Pancreatic duct. 3. Describe 3 ways the body uses these amino acids..
Answer:
1-the gastric enzyme is pepsin, which is why it is a peptidase, since it catalyzes the binding of proteins within the stomach. Its activation method is the acidic pH of the stomach.
2-Pancreatic juice is a juice that hydrolyzes and helps the digestion of proteins or peptides, since this is the EXOCRINE substance of the pancreas, this juice being exocrine is poured into the main pancreatic duct of the pancreas and then through the choledochol in the blister of toilet at intestinal level.
3-amino acids are used by the body for hormonal, transport, and structural purposes. It also has other functions such as the conformation of the same DNA, but there are 3 that must be answered.
Explanation:
Proteins have structures or junctions that are quaternary, tertiary, binary, and primary.
the easiest to degrade with the quaternary and tertiary while the other two do not.
It is important that you know this fact why these structures are ordered from the outside to the inside or inside the protein, the outermost ones are the quaternary ones and the innermost ones are the primary ones.
A protein ceases to be protein and becomes free and separated amino acids when it reaches the heart of the protein and breaks the primary bond, or the sea the strongest and most difficult to break.
These amino acids have multiple functions but they can be said which, when united, are the unit that makes up proteins or peptides.

Answer:
Lycopodium is known as Club moss. It is a vascular plant which makes it an advanced type of plant. It however has some primitive features which includes Production of spores. The plant has an underground sexual reproduction system which produces gametes for this process and also produces spores which are used in asexual reproduction of the plant. The two forms alternate with each other. Another primitive feature is their lack of flowers.
Where does the Energy from plants originally come from?
Answer:
In plants, these energy factories are called chloroplasts. They collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria.

Explanation:
Anaplerotic reactions serve to:__________.
a) divert materials out of the citric acid cycle for use in biosynthesis.
b) regulate energy production by bypassing the citric acid cycle.
c) replenish the citric acid cycle if it becomes depleted of intermediates by biosynthetic demands.
d) produce pyruvate, which initiates the cycle when glucose degradation is not occurring.
Answer: Option C.
replenish the citric acid cycle if it becomes depleted of intermediates by biosynthetic demands.
Explanation:
Anaplerotic reactions that form intermediates for kreb cycle, citric cycle. They form intermediates for metabolic pathways like citric cycle. The citric cycle is important for energy production and biosynthesis. Anaplerotic reactions help to restore or replenish intermediates in citric cycle if there is depletion of intermediates biosynthetic demands.
Someone pls help me to understand what the lock and key theory is for how enzymes work. (use diagrams if it helps)
Answer:
according to this theory both enzymes and substrate possess specific shapes that fit exactly into one another.This model explains specificity.
general example when we open the door of our house we use a specific key to open the door not all keys will open the door of our house.In this example the key is substrate and the door or lock is the enzyme that fits into specific substrate.
what is the job of the stomach, large intenstine, small intestine 60 points!!
Answer:
Stomach - The stomach is a hollow organ, or "container," that holds food while it is being mixed with stomach enzymes.
Large Intestine - The large intestine absorbs water and electrolytes, and produces and absorbs vitamins. It forms and propells feces toward the rectum for elimination.
Small Intestine - The small intestine breaks down food coming from the stomach and absorbs the nutrients from the food.

Why are detritivores, decomposers and omnivores not assigned trophic levels
Answer:
The reason is because detritivores and decomposers and omnivores are multilevel food chain consumers in an ecosystem making them not qualified to be assigned to a given trophic level
Explanation:
An organism is placed in a trophic level based the level it is from where the food chain starts with the start of the food chain having a level of 1 for the food producers such including plants and algae
Level 2 organisms are called primary consumers and consists of organism that eat only plants known as herbivores such as cattle
Level 3 organisms are called secondary consumers and consists of animal eating organism known as carnivores such as foxes etc.
Level 4 organisms are called tertiary consumers
Level 5 organisms are the a p e x p r e d a t o r s
Detritivores and decomposers such as bacteria, earthworm flies fungi consume the wastes produced at all trophic levels, therefore they cannot be assigned to a particular trophic level
Similarly, omnivores consumes both plants at level 2 and animals at level 3 making it ambiguous to assign them to one particular trophic level.
Consider how the following behaviors, characteristics, or facts affect the risk for CVD. Determine whether each increases, decreases, or has no effect on the risk for CVD.
a. Having elevated LDL cholesterol levels
b. having reduced HDL cholesterol levels
c. being a premenopausal woman
d. being exposed to secondhand smoke
e. participating in exercise
f. having elevated HDL cholesterol levels.
Answer:
Explanation:
Having elevated LDL cholesterol levels - this increases the risk for CVD as it also brings about CHD
Having reduced HDL cholesterol levels- this increases the risk of CVD as a low HDL increases omes risk of CVD at lower rates
Being a premenopausal woman - I dont think this has any effect on the risk for CVD
Being exposed to secondhand smoke -
This also increases the risk of stroke associated with CVD
- participating in exercise: this decreases the risk of CVD
Having elevated HDL cholesterol levels - this decreases ones risk of CVD as it helps to clear cholesterol from arteries delivering them back to the lover and reducing the risk for CVD

You discover a new alien race that you decide to call the PAMMARIANS. They are different from us in that they have three sexes, called Q, R, and S. All three sexes must fuse their gametes to form a new PAMMARIAN (and you thought dating on the Earth was hardi). They have nuclear DNA and extrachromosomal organelles, similar to mitochondria, called MITOCHLORIANS, which have their own DNA. The R gender is like human females (they donate the cytoplasm during the mating). Q and S do NOT donate cytoplasm during mating, like human males. Which of the following is TRUE?
A. In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring WILL HAVE a mitochlorian mutant phenotype.
B. In a mating, if the S and a genders have a mitochlorian DNA mutation, the offspring will be mutant as well.
C. In a mating, if only the R gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
D. In a mating, if only the gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring WILL HAVE a mitochlorian mutant phenotype.
E. In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
Answer:
Option E
Explanation:
In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
It was discovered that an offspring always inherits the mothers mitochondrion DNA including all its defects and not from the father as the mother contributes the bulk of the cytoplasm. Thus, since the gender female is R, if she possess a mutant mitochorlian DNA, the offspring will exhibit that mutant phenotype as care to Q and S that cant pass their mutation on.
