First question: B. The net gain of ATP in Photosynthesis is 0, so it cannot be A. C & D are obviously not true. Second question: B. D is not true, C is not true (it is actually the opposite- Chloroplasts absorb all BUT green, so only green would be bad). Like another commentator said, the level of CO2 only aids the rate to a point, at which the rise is ...

I would say Nucleus is the odd one out. Chloroplast (which have Grana in them) and Mitochondria are involved in the process of creating/breaking down energy, whereas the Nucleus is, so to speak, the blue-prints of the cell. To summarize: Chloroplast is involved in Photosynthesis to create energy Grana are in the Chloroplast, which is involved in ...

I believe in small intestine peristalsis is sometimes counted as mechanical digestion as the food is moved along the digestive tract. Chemical digestion occurs with enzymes secreted from the pancreas. https://www.smartlivingnetwork.com/digestive/b/mechanical-and-chemical-digestion/ - source

It depends on what your target tissue is, as @another 'Homo sapien' stated. If you want to get something to the hand, for instance, injecting it into the brachial artery will get it there "faster" than injecting it into the cephalic vein. However, Fastest distribution of some injected materials/medicines & with no risk of any kind does not exist. ...

Thalassemia is a recessive trait. That means individuals with only one copy of the allele (Heterozygotes) have the "normal" phenotype (they don't have Thalassemia). If an individual is homozygous for the recessive allele they will have Thalassemia. Heterozygotes are often referred to as carriers as they can transmit the allele to their offspring, but do ...

The first definition is correct. A sex-linked trait is a trait affected by a locus on a sex chromosome. If you google sex-linked trait, you will find this same definition (not the exact same words) over and over again. The definition of sex-linked trait is NOT restricted to traits that are not unrelated to primary or secondary sexual organs. Any ...

Sex linked traits are those controlled by genes on the sex chromosomes, regardless of whether or not they are related to reproduction. This can be the major (e.g. X or Z) or minor (e.g. Y or W) sex chromosomes. "Sex linkage applies to genes that are located on the sex chromosomes. These genes are considered sex-linked because their expression and ...

From dictionnary.com Genetic: pertaining or according to genetics Hereditary: passing, or capable of passing, naturally from parent to offspring through the genes: Note: I selected the pieces of definitions that I found most relevant to the current discussion. Genetic information can be passed on to offspring. As such, I understand the ...

As I understand your question, you ask about genetic mapping which has been demonstrated in the HGP (human genome project). The human genome project: enabled humans to find the gene responsible for relatively rare, single-gene inherited disorders such as cystic fibrosis and Duchenne muscular dystrophy is useful in guiding scientists to the many genes ...

Expression of the double-sex gene is rather unusual, so it is not surprising that you are having difficulty understand mutations in it. The simplified diagram below (adapted from Gilbert’s Developmental Biolgy — available on-line) should help clarify the matter. The key concept is that although the double-sex gene (dsx) is expressed in both male and ...

I have done lots of research on this in the past few hours and would like to record this for future students to have a look at if they ever require help with a similar question. a) Complete a genetic cross of F2 to show the genotypes and phenotypes of the offspring. We have a two by two grid, with the centre results being TT, Tt, tT, and tt. The phenotypes ...

The intracellular receptor for cortisol is called NR3C1. http://www.uniprot.org/uniprot/P04150 To my knowledge, a direct (competitive) effect of anabolic steroids on the binding of cortisol to NR3C1 has never been proven. The anabolic effects can easily be explained by other targets. A good starting point for further reading might be this review: ...

Generally speaking, there is no effect in microinjections. This is relevant in the real world example of micro-injections. A video of a pronucleus injection can be seen here, or here is a more thoroughly explained procedure involving cloning. As you can see in the video the membrane, almost no effect will be observed - molecular dynamic simulations show ...

I'll bifurcate the question and answer each part one at a time. Germ layer formation: Gastrulation is a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a trilaminar ("three-layered") structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and ...

First of all, 2) mature human RBCs don't have DNA. With the maturation of human red blood cells, the nucleus disappear. DNA is located in the nucleus so mature human RBCs don't have DNA. However, your question didn't say "human RBC". Bird RBC have nucleus thus have DNA. Then, both ovum and sperm cells have nucleus, thus have DNA, no matter which stage ...

In addition to the above answer : Carbon dioxide : Increase in CO2 level in the atmosphere over 0.03 % causes stomatal closure and results in decrease of transpiration.

The correct answer is Monera. It is so because their cell wall is made up of peptidoglycan. Peptidoglycan, also known as murein, is a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consists of alternating residues of β-(1,4) linked ...
