Answer:
Autosomal dominant and recessive: Autosomal dominant states a pattern of inheritance in which an individual carries one normal gene and one copy of a mutant gene while autosomal recessive states a pattern of inheritance in which an individual have two copies of the mutant gene.
Incomplete dominance: Incomplete dominance states a heterozygous condition in which both the alleles present are partially expressed and produces intermediate phenotype.
Codominance: In codominance and individuals receive alleles, if both the alleles are different including dominant and recessive, dominant allele will be expressed while recessive will be masked.
Multiple alleles: organisms with multiple alleles exist with two copies of every gene present in a population with variation in genes.
Sex linked gene: In humans and some other organisms, sex linked genes are influenced by genes on the X chromosome. for example: If a gene is present on the X chromosome only and not the Y chromosome.
Somatic cells in elephants have 56 chromosomes. How many chromosomes would be carried by the gametes produced by elephants
Answer:
As somatic cells are diploid (2n) 2n=56
gametes receive only haploid set so, n=28
The number of chromosomes carried by the gametes produced by elephants would be : 28
Given that The elephants posses 56 chromosomes in its somatic cells and somatic cells are known as diploid cells ( i.e. 2n ) while the gametes will only carry a haploid set of chromosome ( i.e. n ).
Determining the number of chromosomes contained in the gametes
since ; 2n ( chromosomes of a somatic cell ) = 56
∴ n ( chromosomes contained in a gamete ) = 56 / 2 = 28
Hence we can conclude that The number of chromosomes carried by the gametes produced by elephants would be : 28.

In the newly engineered cell created by the researchers at the JCVI, what was derived from a previous cell, partially supporting one aspect of cell theory?
Answer:
Cells can only derive from pre-existing cells.
Explanation:
The cell theory has three major postulates: 1-all organisms are composed of cells, 2-the cells are the basic unit of all living forms, and 3-the cells derive from pre-existing cells. In 2010, the J. Craig Venter Institute (JCVI) designed in the laboratory a synthetic bacterium that is able to auto replicate himself, and thereby supporting the third statement of the cell theory. This bacterium was named as Mycoplasma mycoides JCVI-syn1.0 and its creation represented a milestone in synthetic biology. M. mycoides is a bacterium that has only 473 genes coded by 531,000 bases pairs (bp), this being one of the smallest genomes of all living forms.

help asap true or false Uranus orbits the Sun at less than 40% of the speed of Venus.
Answer:
True
Explanation:
The attached image shows a table that displays the eight (8) planets, their respective average distance from the sun and their respective orbital speeds.
The question only relates the orbital speed of planets Uranus and Venus, which is 7km/s and 35km/s respectively.
40% of the orbital speed of planet Venus is:
= 40/100 × 35
= 0.4 × 35
= 14
According to the table in the image, Uranus orbits around the sun at a speed of 7km/s, which is lesser than 40% of Venus's orbital speed (14km/s).
Therefore, it is TRUE that Uranus orbits the sun at less than 40% of the orbital speed of Venus.

Which is the pair of the enzyme activities most significantly affected by glucagon- and insulin-dependent phosphorylation and dephosphorylation of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFKFB)?
a. hexokinas ::::: glucose-6-phosphatase
b. phosphofructokinase ::::: Fructose-1,6-bisphosphatase
c. pyruvate kinase :::::: pyruvate carboxylase
d. glycogen synthase ::::: glycogen phosphorylase
e. None of these
Answer:
b. Phosphofructokinase; Fructose-1,6-bisphosphatase
Explanation:
Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.
Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).
It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .
It is formed by phosphorylation of fructose-6-phosphate catalyzed by phosphofructokinase-2 and is broken down by fructose-2,6-bisphosphatase which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).
Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.
Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.

Without crossing over, the independent assortment of the homologous chromosomes in a cell with these chromosomes will produce two different genotypes. Which are they
Answer and Explanation:
Crossing over occurs during meiosis. When homologous chromosomes are aligned and they stick together by the chiasma point. At this point, the homologous chromosomes chains break and get recombined with the broken portion of its homologous. The result is that one of the progenitor´s chromosome will have a portion of the other progenitor´s chromosome, and vice-versa.
If crossing-over does not occur, the independent assortment of the homologous chromosomes in a cell will produce two different genotypes that equals the ones of the progenitors. So, there will be two genotypes, one of them equals the female´s genotype and the other is like the male´s genotype.

Explain why chemogenetic based methods of regulating cellular signaling result in poor temporal control of biochemical pathways relative to optogenetic based methods.
Answer:
They use different detecting methods to assess neuronal circuits
Explanation:
Chemogenetics is a technique widely used in neuroscience research to explore signaling interactions by means of genetically modified receptors capable of interacting with small molecules. Chemogenetics was first used to determine the function of the chalcone isomerase gene by inducing mutations that altered its substrate specificity. On the other hand, optogenetics is a bioluminescence-driven genetic technique used to control genetically modified neurons that express light-gated ion channel genes. This technique is also used to monitor neuronal networks. In consequence, optogenetic and chemogenetic techniques have recently been combined in order to analyze neuronal circuits, it by analyzing the same actuator molecule.

Adaptive immunity comprises two branches: humoral immunity and cellular immunity. What are the characteristics of each of the two arms of the adaptive defense system
Answer:
Adaptive or acquired immunity is that we acquire throughout our lives through vaccines (active), breast milk (passive) or injection of specific artificial or natural antibodies to a certain pathogen (passive).
The two great arms of this immunity are the humoral and the cellular.
The humoral refers to the cytokines and immunomodulatory molecules that are responsible for transmitting fundamental messages between defense cells in order to coordinate the destruction of the pathogen between them.
Instead, cellular immunity speaks about cell lineage such as b, t, tcd4 lymphocytes, natural killers, plasmacytes, etc.
It can be said that the humoral factor is the one that coordinates the pathways and the relationships between the cells of the acquired immunity, both are important because the two need each other for adaptive immunity to work.
Explanation:
Examples of the humoral factor: pro and anti inflammatory cytokines, interleukins, complement chain, antibodies, TNF alpha, beta, etc.
Examples of cellular factor: plasmacyst, b lymphocyte, t lymphocyte, NT lymphocyte
