The pairs of base sequences could form a short stretch of a normal double helix of DNA is:

D) 5'-ATGC-3' with 5'-GCAT-3'

In DNA, the code letters are A, T, G, and C, which stand for the chemical substances adenine, thymine, guanine, and cytosine, respectively. Under normal occasions, the nitrogen-containing bases adenine (A) and thymine (T) pair collectively, and cytosine (C) and guanine (G) pair collectively. The binding of those base pairs forms the structure of DNA.

Because of the base pairing, the DNA strands are complementary to each different, run in opposite guidelines, and are referred to as antiparallel strands.

Complementary base pairing is important in DNA because it lets the base pairs be arranged in the maximum energetically favorable way; it's miles crucial in forming the helical structure of DNA. it's also critical in replication as it allows semiconservative replication.

You could determine the sequence of a complementary strand if you are given the series of the template strand. These strands are complementary, with each base in one sticking to its partner on the alternative. The A-T pairs are linked by means of two hydrogen bonds, whilst the G-C pairs are connected through three hydrogen bonds.

Earth's distance and tilt affect the relative amounts of solar radiation regions receive.

Earth's distance and tilt affect the relative amounts of solar radiation regions receive. There are no options provided in the question, but this is the correct answer. The earth's orbit is not circular and the earth rotates in a tilted orbit. Whenever the south pole is tilted towards the sun, then the south pole will get more solar radiation than the north pole. The Earth absorbs most of the energy reaching its surface and a small fraction is reflected. In total, approximately 70% of the incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface.

The correct option that represents the largest to the smallest, in terms of size is a.

D. the diencephalon is where the thalamus is located

Answer:

Explanation:

Kepler's First Law: The orbit of a planet around the Sun (or a satellite around a planet) is not a perfect circle. It is an ellipse—a “flattened” circle. The Sun (or the center of the planet) occupies one focus of the ellipse. A focus is one of the two internal points that help determine the shape of an ellipse. The distance from one focus to any point on the ellipse and then back to the second focus is always the same.

The law of ellipses suggests that the orbit of planets is not circular but ellipses

Therefore your answer would be; Ellipses

Answer:

The law of ellipses suggests that the orbit of planets is not circular but elliptical.

Explanation:

Kepler's first law (the law of ellipses) explains that the orbit of the planets around the sun is not in a circular but elliptical path.

Answer: Base Pair Deletion

Explanation:

If the normal allele has more than the mutated then that means nucleotides were lost so a deletion occurred.

Answer:Base Pair Deletion

Explanation:

We know this because it is stated that the normal gene has more base pairs than the mutated gene. In other words, the mutated gene has less base pairs than the normal gene, which means that base pairs must have been deleted during the mutation.

Let's first define what carrying capacity is:

Carrying capacity is the maximum amount of organisms an ecosystem can carry. It is related to our logistical growth formula:

Where K is our carrying capacity.

Carrying capacity is affected by a couple of things:

0. Resource availability,: depending on how many resources there are in an ecosystem, it can only hold so many organisms.

1. Space,: depending on how ,large, an ecosystem is, the denser the ecosystem (of organisms), the harder it is for the organisms to coexist. Therefore, the smaller the area, the lesser the carrying capacity.

These 2 factors (resources being biotic and space being abiotic) are the only factors few factors that affect carrying capacity.

Therefore, our best answer choice is A.

to answer the question, we will discuss each item:

A) The results obtained during an investigation are information that can be used to design subsequent experiments that will answer questions that could not be answered in the first experiment.

B) The activity of making a prediction before performing an experiment is called hypothesis, which is based on observations. That is, first we will observe the phenomenon, and based on our reasoning we will generate a prediction or hypothesis that we will test with an experiment to see if it is correct.

C) An important part of the research is to have detailed records of each part of the experiment, this way if there is an error we can know in which part of the experiment it occurred and also we can give this information to other researchers so that they can replicate the experiment and confirm the results we obtained.

D) Finally, when the experiment is finished and when we are analyzing the information, we must take all the data into account and not only those that confirm our hypothesis, since that would give us an erroneous conclusion and would be a bias of information. Therefore, the answer is D.

The phrase "he clung to an exposed ledge over the valley from which the train had left" Northridge Junction seems like a desperate person, because out of feeling and/or despair he clung, in this sentence the verb to grab makes it seem like a desperate way not to be in danger of life.

Despair is an emotional state of extreme tension, anxiety and fear.

The person immersed in this state cannot get out easily, because his negative perception contributes to his always being down. When recurrent, it becomes clinical and can take control of emotions.

A hallmark of clinical despair is the meaninglessness of feeling. There are no imminent threats, suffering or dangerous circumstances. Even so, the person experiences this state again and again.

Despair is associated with some mental disorders, such as depression, anxiety, post-traumatic stress disorder, and especially panic syndrome.

Commonly, it is also caused by negative events in the person's life, such as trauma, divorce, dismissal, death of a loved one, abuse, use of chemical substances, among others.

As a protocol, the sample must first undergo primary biochemical tests, one of which is gram staining. And although this stain can help us to identify bacteria of the Clostridium genus, such as gram + sporulated bacilli, a more specific test would be the endospore stain, since the clostridium genus produces endospores that are also easy to isolate, since they are more resistant to temperature than the vegetative form (not sporulated) of the bacterium. An example would be the Schaeffer-Fulton stain.

Explanation:

Chromosomes are structures of nucleic acids and protein carrying genetic information in the form of genes.

The chromosome is composed of two sister-chromatids.

During meiosis and mitosis, the sister chromatids are separated to separate half of the geentic material and create a new cell.

The difference between sister chromatids and non-sister chromatids is that sister chromatids have the same alleles in the same place and non-sister chromatids have different alleles in the same place. Non-sister chromatids will have the same length and configuration, but those different alleles will represent different types of the same characteristic (for example: different colors of fur). But they look the same as sister chromatids.

In order to answer this question, we must remember a bit of cellular metabolism, when mitochondria carry out the process of cellular respiration we can see that in the electron transport chain the final acceptor of electrons is oxygen. Therefore the correct answer for the question is option D oxygen.

The statement that is true is as follows: the density of water is 1 gram per milliliter, so objects with a relative density greater than 1 gram per milliliter will sink (option C).

Density is the measure of the mass of matter contained by a unit volume. The density of a liquid substance is a determinant of whether the substance will float or sink in water.

Water is a liquid substance with a density of 1 gram per millilitres (1 g/mL). This suggests that any substance with greater density than that of water will sink while any substance with lesser density than water will float.

Density is a measure of how heavy something is compared to its size, hence, if an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

Therefore, according to this question, objects with a relative density greater than 1 gram per milliliter will sink.

There are three factors that determine whether a molecule can pass through a cell membrane: concentration, charge and size. The greater the difference in concentration, the more rapid the diffusion. Large and heavier molecules more more slowly so they diffuse more slowly.

B. the concentration of the gas molecules on each side of the membrane.

We have to consider that the DNA is first transcribed into pre mRNA in the nucleus of the cell by the RNA polymerase. After this process, the non-coding fragments (introns) of the molecule are spliced by ribonucleoproteins (snRNP). Eventually, each end of the pre mRNA is modified, being a modified nucleotide named CAP joined to the 5' end, and a polyA (poly Adenine) tail at the 3' end before the now matured mRNA gets out of the nucleus to the cytoplasm.

At this point, the mRNA will be recognized by ribosomes, which will synthesize each group of three nucleotides (codons) into amino acids in a process called translation, by the action of tRNA, and finally joined into a new protein.

Note that A, P, and E are sites of the ribosomes, being A the position where first arrives the mRNA.
