What is the role of a ribosome in protein production?
A. It is the site where amino acids join to tRNA molecules.
B. It is the site where mRNA codons and tRNA anticodons meet.
C. It is the site where a protein strand is folded into its correct shape.
D. It is the site where proteins are packaged and sent where they are needed.
Answers
Answer:
Ribosomes are the sites in a cell in which protein synthesis takes place. ... Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.
Which of the following does not benefit the camel as a means of preventing dehydration?
a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.
Answers
Answer: b
Explanation:
Camels ears are lined with fur to keep out sand and other blowing matter
The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.
What camels are adaptations for heat and dehydration?Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.
Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.
Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

Which statement is correct?
A.
All organisms that can synthesize their food by means of photosynthesis are heterotrophic.
B.
All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
C.
All organisms that cannot synthesize their food by means of photosynthesis are heterotrophic.
Answers
Answer:
B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
Explanation:
There are three ways for a plant to obtain their food, photosynthesis, chemosynthesis, and heterotrophic. Photosynthesis is when the plant makes it's own food. If it can not get it's food from chemosynthesis or photosynthesis, it has to be an heterotrophic plant. The answer to the question is B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.

2.no flowers or fruit
3.no seeds or pollen
4.flowers and fruit
Answers
Answer:
2 is the right answer
Explanation:
they do not produce fruit or flowers think of a pine treee of a spruce tree
Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.
What are gymnosperms?A relatively tiny class of plants known as gymnosperms produce seeds and lack flowers. This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
The Coniferophyta, Cycadophyta, Gingkophyta, and Gnetophyta are the four primary phyla that makeup gymnosperms. Conifers, which have needle-like leaves and thrive in arid, cold climates, are the most common gymnosperm.
Some examples of gymnosperms are ginkgo, pine, melinjo. sago palm, cedars, and spruces. Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.

20. Allosteric effectors: a. can cause large changes in enzymatic activity. b. can lead to a decrease in the availability of a protein. c. do not alter the sensitivity of a metabolic pathway. d. decrease the sensitivity of the enzyme at nearly all concentrations of substrate. e. alter enzyme activity by binding to the active site of an enzyme.
Answers
Answer:
a. can cause large changes in enzymatic activity.
Explanation:
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
Hence, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.
Chromosomal mutations are changes in the normal structure or number of chromosomes. Changes in chromosome structure can result from errors in meiosis or from exposure to radiation or other damaging agents. Certain changes in chromosome number can result from nondisjunction during either meiosis or mitosis. Both structural mutations and nondisjunction can play a role in trisomy 21, commonly known as Down syndrome.
Answers
Answer:
Yes.
Explanation:
Yes, both structural mutations and nondisjunction can play an important role in trisomy 21 which also called down syndrome. In this type of syndrome, extra copy of chromosomes is present in the cell. Down syndrome is a genetic disorder that causes various defects in the children such as learning problems, facial features, vision and hearing problems.

As part of a forensic analysis, you have been asked to determine an individual's ancestry using skeletal indicators. The metric measurements you collect indicate that the individual is of European ancestry, but you see several nonmetric traits in the cranium that are typically found in individuals of Asian ancestry. Why might the two methods give different results
Answers
Answer:
Due to difference in the methods that is used for analysis.
Explanation:
The two methods give different results because we used two different types of measurements i. e. metric measurement and nonmetric traits. In the metric measurement, we calculate the quantitative character of an individual that gives information about the current status of an individual, while on the other hand, in non-metric traits refers to the method which is used to evaluate genetic connections within and between populations that were present in the past.

Answer:

Explanation:
A strain of Drosophila known as dunce produces one-half the amount of cAMP phosphodiesterase found in wild-type flies, which causes a learning defect. Another strain of Drosophila known as rutabaga produces a defective adenylyl cyclase protein (one of the AC types expressed in most cells) and also causes a learning defect. A dunce - rutabaga double mutant fly has relatively normal learning. Explain these curious observations.
Answers
Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.
