Answer:
sea urchin
Explanation:
An echinoderm is an invertebrate animal (without backbones) that belongs to the Echinodermata group. Members of the echinoderm group are characterized by their possession of a star-shaped and spiny-skinned morphology. They are found strictly in marine habitats. They include sea urchins, sea cucumbers etc.
According to this question involving an echinoderm that is covered with movable spines and that eats seaweed, this describes a SEA URCHIN. This is due to the possession of the MOVABLE SPINES by sea urchins. Sea urchins, like other echinoderms, are predatory and feed on seaweed (algae) as well.
Explain why serine proteases do not catalyze hydrolysis if the amino acid at the hydrolysis site is a D-amino acid. Trypsin, for example, cleaves on the CC-side of L-ArgArg and L-LysLys, but not on the CC-side of D-ArgArg and D-LysLys.
Answer:
Explanation:
A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.
SEE BELOW FOR THE APPROPRIATE STRUCTURES.
We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.
The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.
Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.

Suppose you are tasked with determining the protein content of several new cultivars of genetically-enhanced black beans. Which of the following reagents would be particularly useful for your protein isolations?
a) detergent
b) salt
c) cold water
d) acetone
Answer:
The answer is "Choice d".
Explanation:
It is usually used to produce plastics as well as other industrial goods as a solvent. It also is to some extent used throughout the composition of nail polishes in household products, including cosmetic and personal care products. Its separation of proteins form of the plants is a tough process due to the thick cell wall. It is widely used for the precipitate and insulation of proteins. Since it is a relatively cheap substance, this is often employed for protein isolation.

How does sexual reproduction bring about variation
Answer:
The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. ... A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.
The sequence of DNA ACTGGGCGTAAG part of a gene. How many CODONS can be found in the segment
Explanation:
First, think about which base pairs arise in complementary strands of DNA:
DNA → DNA
adenine → thymine (A → T)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
However, mRNA does not consist of the same four bases as DNA. While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG.
So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.
DNA → RNA
adenine → uracil (A → U)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
Giving us the corresponding sequence:
“Scientist have long understood how nutrients move from the oceans surface to its depths. As phytoplankton die, they sink and collect on the ocean floor. But if nutrients are continually sinking to the depths of the ocean, how are surface waters replenished with nutrients? Scientist discovered that in certain regions of the ocean, the nutrients-rich deep water was upwelling, or rising to the surface”
which phrase from the paragraph helps you to understand that ocean health involves steady restoration
Answer:
"As phytoplankton die,they sink and collect on the ocean floor"......."scientist discover that in certain regions of the ocean the nutrients deep water was rising to the surface"
Explanation:
this shows steady restoration of ocean nutrients
As seen that the death of planktons lead to uprise in oceanic nutrients .the cycle just keeps going on and on
its quite self explanatory

What are the REACTANTS in photosynthesis?
[A] Carbon dioxide (CO2), water (H2O), and ATP
[B] Carbon dioxide (CO2), water (H2O), and sunlight
[C] Glucose (C6H12O6) and oxygen (O2)
Answer:
[tex]\boxed {\boxed {\sf B. \ Carbon \ dioxide , water, and \ sunlight}}[/tex]
Explanation:
The reactants are the substances that go into a reaction. You begin with the reactants, then the reaction turns them into different products.
Remember, photosynthesis is a process that certain organisms, like plants, algae, and some types of bacteria, undergo to create "food". They actually produce glucose which serves as an energy source because it is converted into ATP during cellular respiration.
The formula for photosynthesis is:
[tex]6H_2O+6CO_2+ light \ energy \rightarrow C_6H_12O_6 + 6O_2[/tex]
or
[tex]water + carbon \ dioxide + light \ energy \rightarrow glucose + oxygen[/tex]
The reactants are the starting substances, so they are to the left of the arrow. Therefore, the reactants are carbon dioxide (CO₂) water (H₂O), and sunlight. Choice B is correct.
Melanie is asked to list the complementary base pairings of a DNA sample in her lab. What is the MOST appropriate response she can give?
ST, RJ, CO, DI, SE
RFLP and PCR
chromosomes and genes
AT, CG, CG, AT, CG
Answer:
AT, CG, CG, AT, CG
Explanation:
Hi, the answer is the last one, AT, CG, CG, AT, CG.
When we read the question, it says base pairings of a DNA sample in her lab. The only base pairs in DNA is A, T, C, and G.
A is complementary to T, and C is complementary to G.
Therefore, you can eliminate the first three.

If a region on earth has a TEMPERATE climate, which of the following
statements will be true about that region?
O The temperature is usually warm and it rains often.
O
The temperature is usually cold and it rains or snows often.
The temperature and rainfall change at different times of the year.
The temperature is usually cold and there is very little rainfall.
Answer:
The temperature and rainfall change at different times of the year.
Explanation:
A temperate climate region is a territory in which the climate cannot be classified as completely hot or cold, nor rainy or dry, but these characteristics are variable according to the season of the year in which it is found. Thus, these climates do not have extreme heat or cold temperatures, but rather moderate climatic conditions. An example of a region with a temperate climate is the Mediterranean region, the State of Georgia in the USA or Uruguay.

Explanation:
Compare and contrast ocean upwelling and spring and fall turnovers (similarities and differences.
Answer:
Similarity is the circulation of water and the difference is its location where it occurs.
Explanation:
Ocean upwelling is a phenomenon in which dense, cooler, and usually nutrient-rich water from deep water are moved by the wind towards the ocean surface, which replaces the warmer surface water while on the other hand, fall turnover is the time when the water temperature is uniform throughout the water body. Both ocean upwelling and fall turnovers are similar to each other due to circulation of water with the help of wind. Both ocean upwelling and fall turnovers occurs in different location, ocean upwelling occurs on the shore whereas fall turnovers occurs in every part of water body.
