The ________, which stains dark as it contains pigments and blood vessels, is just underneath the retina.
The choroid stains dark as it contains pigments and blood vessels. It is
located underneath the retina. It also lies between the retina and the sclera.
The choroids are very rich in connective tissues( blood vessels) which help
supply the retina with vital nutrients needed for proper eyesight.
The choroids are usually thickest at the extreme rear end of the eye and also helps to maintain a constant eye temperature and volume. This is
important to prevent changes in eye size and temperature which may cause
eye destruction and diseases .

Which statement best describes the subscapularis muscle?
Answer:
b. is correct
Explanation:
The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP
Answer:
ADP
Explanation:
Your question: The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP
My answer: ADP
Why is my answer correct?
If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.
Monosomy: the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.
A trisomy is a chromosomal disorder characterized by an additional chromosome, so the person has 47 instead of 46.
Nullisomic is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2).
So, the correct answer is 'Monosomy'.

to propel itself through its environment
to aid in defense against predators
to assist in the digestion of food
to attach itself to a variety of structures
Answer:
to propel itself through its environment and to attach itself to a variety of structures
Explanation:
I took the quiz(-.-)
Rotifers foot is transformed into a variety of structure for moving and swimming and attach itself to a different structure, hence option d is correct.
What are rotifers?Some rotifers are really planktonic and free-swimming, while others travel around a substrate via inchworming, and some are sessile and reside inside tubes or gelatinous holdfasts.
About 25 species are sessile or planktonic, colonial (such as Sinantherina semibullata), and some rotifer species have evolved four moveable toes that are equipped with pedal glands to facilitate swimming and crawling.
Rotifers swiftly colonize new environments and transform primary production (algae and cyanobacteria) into a form that is secondary consumers.
Therefore foot of the rotifers is changed into a different structure for movement is attach itself to a variety of structures, hence option d is correct.

mendel’s experimental method involved using true breed parental plants for each of the traits he studied in the monohybrid cross. why was this vital to the outcomes of the experiment?
Given what we know about Mendel and his experiments, we can confirm that the benefit of his using true breed parental plants was that it added accuracy and precision to his experiment.
The experiment mentions the use of true breed parental plants for each trait that was studied. A true breed or true-breeding organism is one that will ensure the inheritance of certain physical traits to its offspring through every generation. This is also commonly referred to as a purebred.
The importance of this detail in Mendel's experiments is that it functions as the control variable for the experiment. This is a variable that is maintained constant so that when a change occurs, we can attribute it to other factors and therefore add accuracy to the experiment. Therefore, by starting with purebred parental plants, Mendel could better identify the cause of inheritance for the traits.

how do mitochondria generate and store the energy used to produce most of the atp made during aerobic respiration
Answer:
The citric acid or Krebs cycle processes in the matrix of mitochondria produce a molecule called NADH. NADH is then converted to adenosine triphosphate by enzymes buried in the mitochondrial inner membrane (ATP). Energy is stored in the form of chemical bonds in ATP.
Explanation:
During aerobic respiration, how is ATP created in the mitochondria?Oxidative phosphorylation produces the majority of the ATP produced by aerobic cellular respiration. By pumping protons across a membrane, the energy released by the O2 is utilized to create a chemiosmotic potential. This potential is subsequently used to activate ATP synthase, which converts ADP and phosphate groups into ATP.
What is the mechanism by which mitochondria store energy?Mitochondria (plural: mitochondrion) are membrane-bound cell organelles that provide the majority of the chemical energy required to fuel the cell's metabolic activities. Adenosine triphosphate is a tiny molecule that stores chemical energy created by mitochondria (ATP).
What is ATP's energy storage mechanism?The energy currency of the cell is ATP, or adenosine triphosphate. It retains the energy created during cellular respiration when glucose is oxidized. Energy is stored in the form of high-energy phosphate bonds, which are broken to release energy. Energy is released when ATP is broken down into ADP and Pi.
