When a DNA molecule is replication, it is hemimethylated. soon after, the newly made DNA strand is methylated by methyltransferase.

When a DNA molecule is replicated, it results in two daughter DNA strands. These two strands are initially hemimethylated, which means that only one of the DNA strands retains the methyl groups while the other strand is newly synthesized and lacks methylation. Soon after replication, the newly made DNA strand is methylated by an enzyme called DNA methyltransferase.

DNA methyltransferase is responsible for adding methyl groups to the DNA molecule, specifically to cytosine residues in a CpG dinucleotide context. This process is part of the epigenetic regulation of gene expression and plays a role in various cellular processes, including development, differentiation, and the maintenance of genomic stability.

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 

1.photosynthesis

2.chlorophyll

3.sun light

4.carbon dioxide

Plants need several molecules to make glucose during the process of photosynthesis. The correct answers include:

Carbon dioxide (CO2): Plants take in carbon dioxide from the air through small openings called stomata on their leaves.

Water (H2O): Plants absorb water from the soil through their roots and transport it to their leaves.

Sunlight: The energy from sunlight is captured by chlorophyll, a pigment found in the chloroplasts of plant cells, and is used to power the photosynthesis process.

Chlorophyll: Chlorophyll is a green pigment found in the chloroplasts of plant cells that absorbs light energy and converts it into chemical energy, which is used to make glucose.

Therefore, the correct answer is (1) Carbon dioxide, (2) Water, (3) Sunlight, and (4) Chlorophyl

Explanation:

Anaerobic respiration does not need oxygen to occur and aerobic respiration does after glycolysis, the pyruvate molecules can follow two different metabolic routes.

During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise. As byproducts, carbon dioxide and water are produced. The Krebs cycle, oxidative phosphorylation, and glycolysis—an anaerobic process—are the three phases of aerobic cellular respiration. Some organisms can continuously convert energy even when there isn't any oxygen present. To produce ATP, they first go through glycolysis and then anaerobic fermentation.

1)A. The neuron uses saltatory conduction to transmit action potentials.

2)b) The neuron would not be able to release neurotransmitters.

3)d) The synapse becomes weaker, requiring spatial summation from multiple presynaptic neurons to recall the memory.

4)b)It will create an IPSP, inhibiting the postsynaptic neuron.

5)a) The thalamus has stored the information into short-term memories.

The process of long-term potentiation (LTP), which involves continuous synaptic strengthening, results in a sustained increase in signal transmission between neurons. In terms of synaptic plasticity, it is a significant process. LTP recording is a well-known cellular model for the investigation of memory.

The AMPA and NMDA receptors are two of these subtypes that are particularly crucial for LTP. When glutamate binds to the AMPA receptor, an ion channel that is connected to it opens, allowing sodium ions to enter the post-synaptic neuron.

Based on the provided hint, in order to determine whether a tall pea plant is homozygous or heterozygous for tall height, the other contributing parent genotype must be heterozygous for tall height.

In the example about dog deafness, it was explained that the deafness in dogs is a recessive trait, and the deafness genotype is dd.

If a deaf dog is crossed with a hearing dog, the deaf dog must be homozygous for the deafness allele (dd), and the hearing dog must be heterozygous (Dd) for the deafness allele in order to determine whether the offspring will be deaf or not.

Similarly, in order to determine whether a tall pea plant is homozygous (TT) or heterozygous (Tt) for tall height, it must be crossed with a pea plant that is known to be heterozygous for tall height (Tt).

If the offspring are all tall, the tall parent is likely homozygous (TT) for tall height. If the offspring are a mix of tall and short plants, the tall parent is likely heterozygous (Tt) for tall height.

Answer: The correct answer is C...I made a typo error in my original so i want to make clear that it is C. A process by which water moves from Earth's surface into the sky and back again

Explanation:

The water cycle is a process involving precipitation, evaporation, and condensation.

This is the concept in a nutshell:

Precipitation is rain/snow/sleet, but mostly classified as rain. It means when the water in the clouds rains down and hits the ground. Evaporation is the process of the water that hits the ground invisibly going back up into the sky and drying from the ground. From this point, the evaporated water condenses into clouds, hence the name condensation. From this point forward, the water precipitates again, evaporates again, condense again, and repeat

The probability of their child having dimples is 3/4 or 0.75, which is equivalent to a 75% chance, as in the gene and both parents being heterozygous.

The gene for dimples is a dominant trait, which means that if an individual inherits at least one copy of the dominant allele, they will express the trait. In this scenario, both parents are heterozygous, meaning they each carry one dominant allele and one recessive allele.

Since both parents are heterozygous, they each have a 50% chance of passing on the dominant allele (D) and a 50% chance of passing on the recessive allele (d) to their offspring.

To calculate the probability of their child having dimples, we can use a Punnett square to determine the possible genotypes of their offspring.

In pea plants, the allele for having round peas (R) is dominant over the allele for having wrinkled peas (r). In a Punnett square, the genotype of one parent is written along the top, and the genotype of the other parent is written along the side.

When a pea plant with RR genotype is crossed with a pea plant with Rr genotype, the Punnett square would look like this:

R - R

R - r

Square 1 would have the genotype of Rr and square 2 would also have the genotype of Rr. The R allele codes for round peas, and the r allele codes for wrinkled peas.

When a pea plant with the genotype RR is crossed with a pea plant with the genotype Rr, the offspring will all have the genotype Rr, which means they will all have the round pea phenotype (R is dominant over r). So, the squares marked 1 and 2 should have Rr written in them.
