Flowering Locus C (FLC) is a gene that is responsible for flowering in certain plants. FLC is expressed in new seedlings, which prevents flowering. Upon exposure to cold temperatures, FLC expression decreases and the plant flowers. FLC is regulated through epigenetic modifications. What type of epigenetic modifications are present in new seedlings and after cold exposure
Answer:
- New seedlings: histone acetylation
- After cold exposure: histone methylation
Explanation:
Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In Arabidopsis, vernalization is associated with histone modifications at FLC chromatin. The FLOWERING LOCUS C (FLC) is a MADS-box gene that acts as a repressor of flowering in Arabidopsis. Epigenetic modifications control the expression of the FLC gene. The FLC gene is expressed at low temperatures due to histone acetylation at FLC chromatin, and thereby the expression of FLC mRNA transcripts ensures that the Arabidopsis plant cannot flower. Subsequently, as the Arabidopsis plant is exposed to cold, FLC is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.
describe an acquired trait, and how is it related to the environment
Answer:
Explanation:
A trait that is not inherited; one resulting from the effects of the environment. See also: trait.
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence.
Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.
A farmer uses a chemical spray to kill the weeds in his garden. Some of the spray is carried by the wind into his pasture and the grass is killed. What will happen to the population of grasshoppers in the grass dies off?
Answer:
B: The Grasshopper population will decrease
Explanation:
Make me brainliest please
The Grasshopper population will decrease if population of grasshopper dies off.
What is Chemical spray?
population ecology and making predictions about population dynamics would be sufficiently challenging based only on the complicating qualities that living entities bring to the problem (variation and history), but an ecologist must also taken into consideration the particularities of a given system.
Grasshoppers cause serious economic damage to both crops and rangeland, although the greatest concern has been with respect to losses of livestock forage in the latter system (Hewitt and Onsager 1983, Joern and Gaines 1990).
What is lacking, however, is any substantive advance with regard to state and federal forecasting of rangeland grasshopper population dynamics that would allow limited resources to be acquired, allocated, and applied in an optimal manner.
Therefore, The Grasshopper population will decrease if population of grasshopper dies off.

Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Answer:
Correct
Explanation:
Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.
The Homoeostatic feedback mechanism has three basis components and they are independent to one another.
These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.
So, the order in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.
Before cellular division, the cell must duplicate its DNA so that the daughter cells will contain complete copies of the dna. Which characteristic of DNA makes it most suitable as a molecule for this role?
A. DNA is located in the nucleus
B. DNA is a large macromolecule
C. DNA is made of repeating sugar-phosphate subunits
D. DNA is made of two strands of complementary nucleotides
Answer:
D. DNA is made of two strands of complementary nucleotides
Explanation:
As rightly stated in this question, DNA replication must occur prior to cell division because each daughter cells must receive an equal and correct amount of genetic material (DNA). DNA replication is the process by which the DNA molecule duplicates to form two identical copies of itself.
This replication characteristics of DNA is achievable because "DNA is made of two strands of complementary nucleotides". The double-stranded DNA first unwinds into two single strands. After which, each single strand serves as a template for the new DNA strand. Two strands of a DNA molecule are complementary to one another.

Rabies, typhus, and malaria are _____. all untreatable transmitted by animal bites diseases which have been eradicated caused by viruses
Answer:
Transmitted by Animal bites
Explanation:
Typhus= Fleas
Rabies= Any animal that is severely sick
and if bitten can kill you if not treated immediately
Malaria= Mosquitoes
Rabies, typhus, and malaria are transmitted by animal bites all untreatable transmitted by animal bites diseases which have been eradicated caused by viruses.
What is virus?
Virus is defined as infectious agent of small size and simple composition that can multiply only in living cells of animals, bacteria or plants.
Rabies is usually spread through an animal bite. Animals most likely to spread rabies include dogs, coyotes, bats, foxes, skunks, and raccoons.
Typhus fevers are a group of diseases caused by bacteria that are spread to humans by lice, fleas, and chiggers.
Malaria is an intermittent and remittent fever caused by a protozoan parasite that invades the red blood cells. The parasite is transmitted by mosquitoes in many tropical and subtropical regions.

Answer:
If the parents were both carriers.
Explanation:
Since cystic fibrosis is a recessive genetic disorder, two of the same alleles must be present in order to show, so.. for example, the genotype would be cc. The parents without the disorder must've been carriers, and their genotype would be Cc.
If you do a punnet square, Cc x Cc = 25% cc, 50% Cc, and 25% CC.
