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
Answers
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.
Sara is learning about photosynthesis and cellular respiration in her science class. Which statement can Sara write that best explains the relationship between
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
Answers
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.
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
Answers
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.

Since, during transcription RNA codes for the coding strand only then why are there introns in mRNA in eukaryotes????????
Answers
Answer:
Intron is essential for coding of proteins and hence it is present in the mRNA of Eukaryotes
Explanation:
Intron are important for coding proteins. In eukaryotic cell, the mRNA has introns and these introns are removed by encoding proteins from mRNA with a right sequence. Thus, introns are essential to encode DNA, RNA, protein etc, and they take partly important roles during encoding of mRNA to higher forms of molecules.

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
Answers
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?
Answers
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.

state whether volcanoes are evenly distributed over earth’s crust or concentrated in specific areas
Answers
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.
A ___(J)_____ is a group of individuals of the same species that mate and produce offspring. In each generation, new genotypes occur that express themselves as specific individual ____(K)___. Any factor that affects the ____(L)___ of a population can change the frequency of ___(M)___, resulting in evolution over time. Through the processes of variation and ___(N)___, new species can arise. A ___(P)___ is a population of physically similar, interbreeding organisms that do not interbred with other such groups.
Answers
Answer:
(J) population; (K) phenotypes; (L) gene pool; (M) alleles; (N) natural selection; (P) species
Explanation:
A population is a group of organisms living in a particular geographical area that is capable of interbreeding, while a species is a group of populations that are capable of interbreeding and producing fertile progeny. In a population, genetic variation can enter from one of these sources: 1-recombination (i.e., the exchange of DNA between homologous chromosomes during meiosis), 2-mutations (i.e., genetic alterations resulting from DNA replication), 3-migration of individuals between populations, or 4-lateral or horizontal gene transfer (i.e., the acquisition of genetic material between individuals without direct vertical inheritance, it is extremely rare in higher organisms). Alleles are gene variants which are may be created, for example, through mutation, while the gene pool refers to the total genetic diversity (i.e., alleles) that exists within a population. Finally, natural selection refers to the evolutionary process of differential reproduction and survival through which populations adapt and change.
