Answer:
The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
Explanation:
The Hawaiian Islands are the chain of eight major islands situated in U.S. of Hawaii. These are formed over a hot spot. About 75 million years ago such hotspot took place in the center of the Pacific Plate.
There are hot spot due to the volconic activity and in the moving over the tectonic plate of a subduction zone. Volcanic activity and overriding of plates that cause rising magma by melting the moving down plates whice leads to volcanic arcs formation. The magma that rose gradually cooled down and become solid over the time. It is an example of a large seamount and island chain created by hot-spot volcanism.
Thus, The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.

Consider a system in which low levels of protein "Q" triggers production of hormone A. The reaction of target cells of hormone A is to produce and release hormone B, which stimulates production of hormone C. In response to hormone C, the target cells up-regulate protein Q. In this scenario we see an example of _____.
Answer:
Negative feedback
Explanation:
Negative feedback is produced when a mechanism is amplified through an inverse loop, which tends to reduce the fluctuations in the system. In this case, the negative feedback mechanism represents a homeostatic response of the body where the release of a target hormone (hormone C) decreases in response to the increase of a protein (protein Q) upstream in the signaling pathway. Therefore, in this scenario, it is expected that negative feedback causes a decrease in hormone function.
Consider the following chromosomes and if they are affected by hemophilia. X - unaffected X chromosome, x = X affected by hemophilia, and Y = Y chromosome. If an Xx female and XY male have children, what fraction of their offspring will have an affected chromosome, and what fraction is likely to be affected by the hemophilia? (1 point) A. 1/4 and 1/2 B. 1/2 and 1/4 C. 1/2 and 1/3 D. 1/4 and 1/4 Ive been stuck on this for a while now, can someone please assist?
Answer:
B. 1/2 and 1/4
Explanation:
Hemophilia is a disease inherited in humans. It is only carried on the X chromosome, hence, it is said to be X-linked. In this question;
X - unaffected X chromosome
x = X chromosome affected by hemophilia,
Y = Y chromosome
Hence, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:
Xx- X and x gametes
XY- X and Y gametes
Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY are produced.
XX (1) - unaffected normal female
Xx (1) - unaffected carrier female
XY (1) - unaffected normal male
xY (1) - affected male
Based on the questions;
- 2 out of the possible 4 children have the affected chromosomes i.e. both xY son and Xx daughter have the x chromosome. Hence, the fraction is 1/2
- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

What has a greater influence on protein levels?
(1 point)
Protein degradation has a greater influence because outside factors like antibiotics can
cause it, and it is difficult to recover from.
O
Protein degradation has a greater influence because they are denatured faster than the cell
can produce them.
mRNA destroyer concentration has a greater influence because it is destroying mRNA before
proteins can even be produced.
mRNA destroyer concentration has a greater influence because mRNA is destroyed right
after the proteins are produced.
Answer:
mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced.
Explanation:
Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.
Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.

(2)2/√6
(3)√36/1296
(4)-√6+6
Explanation:
hi !!
here i think all areirrational expect root 36/1296,
1. root 2= root 2= 1.414213562
2. 2/root 6= root 6 /3 = 0.8164965809
3. root 36/1296=1/6=1.66666667
4. - root 6+6= -2 root 3 = -3.464101615
so, they are extended and dont have exact value so all are irrational expect no. 3 because it can be expressed in 1/6 fraction form but others will come on root form.

How are the molecules in photosynthesis and cellular respiration similar? Please include descriptions of the molecules
Answer:
They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
They exhibit the same responses, but they do so in reverse. Carbon dioxide and water are converted during photosynthesis into glucose and oxygen. Carbon dioxide and water are produced during respiration in exchange for glucose and oxygen.
What similarity in photosynthesis and cellular respiration?Energy transformations from one form to another are a part of both respiration and photosynthesis through a sequence of metabolic reactions.
The reactions that are carried out by both processes—which both use and produce ATP—are carried out on membranes and are managed by enzymes.
Light energy is converted by photosynthesis into chemical energy that is stored in glucose, which is then released by cellular respiration to create ATP, the life-sustaining compound.
Therefore, They are similar because they both produce energy, but in two different forms.

How are the proteins inside your body affected by the presence of water and other molecules?
Answer:
Our body is constitute of several essential molecules such as proteins, fat, carbohydrate, water, and other molecules.
Each molecule has some of the impact of other molecules in the body. Impact of water and other molecules on proteins inside the body are as follows:
Proteins have ligand-binding site and water provide stability to the ligand-binding site of proteins through its hydrogen bonds.Conformational flexibility and transitions of proteins are due to the presence of water molecules in it.Disbalance in the pH of body due to changing concentration of sodium-potassium ions can denature the protein. Enzymes present in the body can control the rate of formation of proteins in the body.

what are sex hormones?why are they named so? state their function.
Answer:
Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.
The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.
In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.
Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question... Thank you for the question.
