state whether volcanoes are evenly distributed over earth’s crust or concentrated in specific areas
Answer: Concentrated in certain areas
Explanation:
Volcanoes are usually formed as a result of collisions or other activity between plates at plate boundaries.
As a result, they are more usually concentrated in zones where there is more plate activity such as at the edges of continents, on islands and beneath the seas in certain areas because this is where plates usually collide with each other.

Because there are three different possible reading frames in a messenger RNA (mRNA) molecule, most mRNAs can be translated in a cell into three different proteins. true false
Answer:
False
Explanation:
In the genetic code, each triplet of nucleotides (i.e., each codon) determines one specific amino acid or one-stop codon. The genetic code is not overlapping, which means that the same letter in the genetic code (nucleotide) cannot be used for two different codons. There are 64 possible combinations of triplets of nucleotides, 61 of them determine amino acids, while three triplets determine stop codons (UAG, UAA, and UGA) that indicate the termination of translation. Moreover, the genetic code is also degenerate, which means that one amino acid can be coded by more than one codon.

these two processes?
O A. The chemical reactions of photosynthesis and cellular respiration could not take place without each other.
B. Photosynthesis and cellular respiration are chemical processes used in both animal and plant cells.
C. Plants use photosynthesis to produce food, while animals use cellular respiration to consume their food,
D. When cells do not have enough energy for respiration, they rely on photosynthesis.
oh
Answer:
The most suitable answer is C.
Explanation:
Photosynthesis is the process whereby plants manufacture their own food using water, carbon (iv) oxide and some other minerals in the presence of sunlight while cellular respiration is the oxidation (or breakdown) of substances in the mitochondria (site of cellular respiration) in living cells.

If someone called you a diploid, why would you not be offended?
Answer:who knows
Explanation:
2. Which of the following best describes the genetic material a person receives from his or her father?
- 22 pairs of homologous chromosomes and an X and Y chromosome
- 22 haploid cells and an X or Y chromosome
- 23 diploid cells and an X and Y chromosome
- 22 autosomes and an X or Y chromosome
Answer:
22 autsomes and an X or y chromosome
Explanation:
Humans have 46 chromosomes. 23 from the mother and 23 from the father. The father has x and y chromosome. While the mother has two x chromosomes. 22 chromosomes each are given from both parents And the other chromosome (the 23rd) are the chromosomes for sex genes. Autosomes are all chromosomes that are not sex chromosomes. Therefore 22 autosomes are given from each parent. With reference to this questions 22 autsomes and one x or y chromosome will be given from the father.
How do heterotrophs get their source of glucose?
Answer:
By consuming plants and animals.
Explanation:
Since plants are autotrophs, they absorb the sun's energy through photosynthesis and make glucose. herbivores (plant eating heterotrophs) then consume these plants and gain energy from the glucose and further up the food chain carnivores consume herbivores and also gain a bit of glucose from them.
in garden peas, yellow seeds (y) are dominant to green seeds (y), and inflated pods (i) are dominant to constricted pods (i). suppose you have crossed yyii parents with yyii parents. draw the f1 punnett square and predict the expected f1 phenotype(s). list the genotype(s) of gametes produced by f1 individuals. draw the f2 punnett square. based on this punnett square, predict the expected phenotype(s) in the f2 generation and the expected frequency of each phenotype.

In garden peas, yellow seeds (Y) are dominant to green seeds (y), and inflated pods (I) are dominant to constricted pods (i).
Suppose you have crossed YYII parents with yyii parents.
Draw the F1 Punnett square and predict the expected F1 phenotype(s). List the genotype(s) of gametes produced by F1 individuals. Draw the F2 Punnett square. Based on this Punnett square, predict the expected phenotype(s) in the F2 generation and the expected frequency of each phenotype.Answer:
F1 phenotype ⇒ 100% plants heterozygous for both traits, expressing yellow seeds and inflated pods, YyIi. F1 gametes ⇒ YI, Yi, yI, yiF2 Phenotype ⇒ 9/16 are expected to be plants with yellow seeds and inflated pods, Y-I-3/16 are expected to be plants with yellow seeds and constricted pods, Y-ii3/16 are expected to be plants with green seeds and inflated pods, yyI-1/16 are expected to be plants with green seeds and constricted pods, yyiiExplanation:

When we make a pass among true-breeding mother and father having yellow colour seed, and inflated pods with true-breeding determine have inexperienced colour seed and constricted pods, then withinside the F1 technology we get -
The genotype of a true-breeding determines having a yellow colour seed, and inflated pOds=YY||.The genotype of a true-breeding determined to have inexperienced colour seed and constricted pods = yyii.A pass among YYII (Yellow, inflated) x yyii (Green, constricted).Gametes are made out of a mother and father having genotype YY|I=YI.Gametes are made out of a mother and father having genotype i = Yi.1st cross :

A host cell infected by a virus will activate the adaptive immune response through _______. (Select all that apply) Dendritic cell Macrophages MHC I molecules Cytotoxic T cell MHC II molecules Helper T cell
Answer:
Cytotoxic T cell
Helper T cell
Explanation:
Adaptive immune system is a part of the immune system initiated only when there is an attack by a pathogen or foreign substance. The adaptive immune system is beckoned on when the infection is insurmountable for the body's first line of immunity, which is the innate immune system.
The adaptive immune response is triggered by the white blood cells called LYMPHOCYTES. Lymphocytes consists of T cells and B cells. T cells are either cytotoxic or helper T cells. The cytotoxic T cells kills the cells infected with the virus while the Helper T cells activate every other cell involved in the immune process.
