If one half of a DNA molecule has 8 thymine bases, what else is also true about the DNA molecule? (1 point)
There will be 16 total bases.
O There will be 32 total bases.
There will be 8 adenine bases.
There will be 8 cytosine bases.

Answers

Answer 1
There will be 8 adenine bases.

Thymine always pairs with adenine in DNA, so if there are 8 thymine bases that means there are also 8 adenine bases.

We don’t know how many total bases there will be, and because cytosine does not pair with thymine we don’t know how many cytosine bases there will be.

Human actions often break large areas if forest or grassland into small remnant parcels that support fewer individuals and ae far apart from one another. Predict how gene flow, genetic drift, and extinction risk would differ between the original and the remnant populations.

Answers

Answer:

Gene flow will be restricted

Gene drift will be higher than in larger populations

Extinction rate will be increased due to the reduction in genetic diversity

Explanation:

Gene flow is defined as the transference of genetic material among populations. In isolated populations, the gene low is null and thereby they have different allelic frequencies, while populations that share genetic material tend to have the same allelic frequencies.

Genetic drift is the change in the allelic frequencies in a population as a result of random sampling. In small populations such as those living in parcels, the genetic drift is higher than in larger populations.

Extinction is the continuous declination in the number of organisms of a particular group (for example, a population or a species), that inevitably leads to the disappearance of this group. In small populations, the likelihood of extinction will be higher than in larger populations, due to the lesser genetic variation and higher genetic drift.

Given the gene sequence GGACCGTCGATCTTC, which of the following choices would represent an inversion mutation? A. GGACTCGATCTTC B. CCACCGTCGATCTTC C. GGACCGTCGATCTTC D. GGACCGTCGATCCTT

Answers

Answer:

D. GGACCGTCGATCCTT

Explanation:

Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.

Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.

Answer: GGACCGTCGATCCTT

Explanation: mutation means change and there is change in the gene sequence

During the Paleocene-Eocene Thermal Maximum, when global surface temperatures spiked, we observe temperate forests ____________________, insect herbivory of temperature.

Answers

Answer:

The overview of the problem concerned is listed below.

Explanation:

Mostly during Paleocene Eocene Temperature Optimum, we consider temperate vegetation momentarily relocated towards the poles whenever global average surface temperature jumped, bug harvesting temporarily escalated, as well as coral reef crashed.The level of variations in climate or temperature was as sluggish as it is today, which suggests that such past occurrences are likely to overestimate the effects of rising temperatures nowadays.

Increase occur in the insect's population due to increase occur in global surface temperature.

During the Paleocene-Eocene Thermal Maximum, when global surface temperatures increase, we observe temperate forests having more population of insects due to favourable temperature for the growth of insects.

The productivity and distribution of forests could be affected due to change occur in the temperature, precipitation and the amount of carbon dioxide in the air. As the temperature increases the population of insects also increases which leads to increase in biodiversity of forest so we can conclude that increase occur in the insect's population due to increase occur in global surface temperature.

If a father is affected by an X-linked dominant condition and the mother is not, which children can inherit the condition?
only males
neither males nor females
only females
O both males and females

Answers

Answer:

only females

Explanation:

In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.

Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).

N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.

Answers

Answer:

They are responsible for determining the general body plan.

They act as master control genes.

They code for DNA-binding proteins.

Explanation:

The homeotic genes are master regulators in development found both in animals and plants. In animals, Homeobox (HOX) genes encode for transcription factors containing a DNA binding domain of 60 amino acids which is evolutionarily conserved in species ranging from Drosophila to humans. In plants, MADS-box homeotic genes encode for proteins containing a conserved DNA-binding domain (in this case, referred to as MADS-box of 60 amino acids), which is capable of controlling developmental pathways in a similar mode to Hox genes in animals. Moreover, it is important to note that MADS-box genes are conserved not only in plants but also in other phyla including animals, fungi and protists.

The main function of a cell membrane is to allow substances to enter and leave the cell. Which is a correct description of transport through a cell membrane

Answers

Answer:

The question is incomplete, below is the completed question:

The main function of a cell membrane is to allow substances to enter and leave the cell. Which is a correct description of transport through a cell membrane ?

a. Diffusion, or passive transport, occurs when molecules diffuse from a lower concentration to a higher concentration.

b. Facilitated transport occurs when proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion.

c. The lipid bilayer opens up and allows the ions or molecules to enter the cell, then closes.

d. Active transport occurs when molecules diffuse from a higher concentration to a lower concentration.

Answer:

b. Facilitated transport occurs when proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion.

Explanation:

Transport through cell membranes can be broadly classified as active transport or passive transport.

Active transport requires energy in the form of ATP for the transportation of substances across the cell membrane.

Option b correctly describes facilitated diffusion, which is a passive-mediated diffusion process, where channels in the cell membrane mainly composed of proteins called transmembrane integral proteins, allow for the movement of certain molecules (mostly polar/hydrophilic) molecules that will not otherwise be transported through simple diffusion because of the hydrophobic nature of the cell membrane.

The other options are wrong because:

a. diffusion or simple transport involves the movement of substances from regions of higher to a lower concentration not lower to higher as suggested here.

c. The lipid bi-layer does not allow ions or hydrophilic molecules because it is hydrophobic in nature, and it is not a channel, so it does not open and closes

d. In active transport, transfer of molecules is from regions of lower to higher concentration and not higher to lower concentration as suggested here.

The maternal effect is a genetic phenomenon that is characterized by an organism having the phenotypic expression that is compatible with the genotype of its mother irrespective of the organism's genotype itself.

This condition often occurs as a result of the mother supplying messenger RNA or protein to the egg that results in the formation of a zygote/embryo. Consequently, the genome of the mother dictates the functionality of the molecule in such offspring.
