When you smoke a cigarette, the components; e.g. nicotine and carbon monoxide enter the lungs and are absorbed into the bloodstream. They are carried by the Red Blood Cells to the blood-brain barrier, here, nicotine binds to nicotinic acetylcholine receptors (nAChRs), resulting to a cascade that results to release of dopamine (good-feeling neurotransmitter).

A scientific paper that has passed through the peer review process is more respected than one that has not. Why might a scientist value a peer-reviewed paper?
A. The analysis of the experimental results is guaranteed to be entertaining.
B. The described experiment meets or exceeds the standards of good science.
C. The scientist who wrote the paper is likely to become a famous person.
D. The described materials are expected to become a good investment.
The correct answer is B. The described experiment meets or exceeds the standards of good science.
Explanation:
In science, it is common after research scientists publish information about the process and results in scientific papers or articles. Additionally, the credibility and reliability of this documents and of the research itself depend on multiple factors and one of this is whether the paper has been review by another expert in the field which called peer-reviewed paper. Indeed papers that have gone through the peer-review process are more credible and therefore more value by other scientists as in general terms this guarantees the results can be believed as each step in the research fits with the standards of good science because the scientists who reviewed the paper approve it. Therefore, the reason a scientist value a peer-reviewed paper is that the escribed experiment meets or exceeds the standards of good science.

The method by which lymph is pushed through the lymph vessels is via
Lymph is moved through lymph vessels by skeletal muscle contractions, varying external pressures, and one-way valves that prevent backflow, as the lymphatic system lacks a central pump like the heart.
The method by which lymph is pushed through the lymph vessels is via a combination of movements caused by skeletal muscle contractions, external pressures, and the one-way valves present in the lymphatic system. Blood pressure at the capillaries initially forces plasma into the lymph spaces, where it becomes lymph and exerts pressure on the walls of the lymph vessels. This lymph then moves through the network of lymphatic vessels primarily due to the contraction of skeletal muscles around these vessels as the body moves, and the one-way valves that prevent backflow of lymph, ensuring it flows in the correct direction towards the heart.
Lymphatic capillaries absorb this fluid from the tissues and transport it through larger lymphatic vessels to eventually reach the two large lymphatic ducts in the upper chest. From there, lymph enters the circulatory system by flowing into the subclavian veins. The lymphatic circulatory system does not have a central pump like the heart in the cardiovascular system, hence the reliance on muscle contractions and movement to propel lymph through the body.

A horse does 860 J of work in 420 seconds while pulling a wagon. What is the power output of the horse? Round your answer to the nearest whole number.
The power output of the horse is
W.
Answer:
Power output, P = 2 watts
Explanation:
It is given that,
Work done by a horse, W = 860 J
Time taken, t = 420 seconds
We need to find the power output of the horse. Power output is given by work done divided by total time taken i.e.
[tex]P=\dfrac{W}{t}[/tex]
[tex]P=\dfrac{860\ J}{420\ s}[/tex]
P = 2.04 watts
or
P = 2 watts
So, the power output of the horse is 2 watts. Hence, this is the required solution.

By the time the fertilized human reaches the uterus, the rapidly dividing ball of cells, now known as a blastocyst, has separated into two sections. The inner group of cells will become the embryo. The outer group will become the cells that nourish and protect it. On contact, it will burrow into the uterine wall for nourishment. This process is called
This process is called implantation.
During the process of implantation in humans, the developing embryo (rapidly dividing ball of cells) is known as a blastocyst. The blastocyst divides into two parts to form the embryo and placenta. The embryo attaches to the wall of the uterus in order to receive oxygen and nutrients from the mother for its growth. The embryo remains attached to the uterus until birth. The process of implantation is completed by day 9 or 10.
How does karyogram B differ from karyogram a
They differ in sex chromosomes.
Explanation:There are two types of chromosomes; autosomes(22 pairs) and sex chromosomes(1 pair).
While all the autosomes are same in the case of both male and female humans, sex chromosomes differ.
Human male has one X and one Y chromosome, while human female has two X chromosomes. Y is roughly shorter by half than the X chromosome.
Final answer:
Karyogram B may differ from karyogram A by having an extra chromosome (aneuploidy), missing a chromosome (monosomy), or displaying structural changes such as translocations. These alterations can be identified by comparing chromosome size, banding patterns, and centromere positions.
Explanation:
A karyogram is a visual representation of an individual's chromosomes, organized into homologous pairs. It shows the chromosome number, size, banding patterns, and centromere positions of a person's chromosomal makeup. Karyogram B is likely to differ from karyogram A in aspects such as the presence of an extra chromosome, which is a condition known as aneuploidy, the lack of a chromosome referred to as monosomy, or structural changes like translocations. To identify these differences, each chromosome is compared for size, banding pattern, and centromere position.
Karyogram B might show a genetic abnormality that can lead to various health conditions depending on which chromosome is affected and how it is altered. For example, if karyogram A is normal, and karyogram B displays an extra chromosome 21, this would be indicative of Down syndrome. Such comparisons are crucial in genetics and medicine for diagnosing chromosomal disorders.
Sexual reproduction requires cells to undergo ______, whereas only _______ is necessary for asexual reproduction. meiosis; mitosis mitosis; fertilization fertilization; meiosis mitosis; meiosis
Answer:
Sexual reproduction requires cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction.
Sexual reproduction involves germ cells these are the cells which gives rise to gamates. Germline diploid cell undergoes meiosis to develop four haploid daughter germ cells. Asexual reproduction takes place in those organisms which cannot produce specialized cells for reproduction. Therefore, the cells undergo simple cell division for reproduction. In asexually reproducing cells mitosis takes place, in which one cell gets divided into two daughter cells.
In sexual reproduction, meiosis is required to halve the number of chromosomes, allowing for the combination of genetic material during fertilization. In contrast, asexual reproduction only involves mitosis to create identical daughter cells from a single parent.
Explanation:Sexual reproduction requires cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction. In sexual reproduction, genetic material is combined from two parents to create offspring. This process involves a type of cell division called meiosis where the number of chromosomes is halved, allowing for the combination of genetic material during fertilization. On the other hand, asexual reproduction involves a single parent and does not involve the fusion of gametes. This process requires mitosis, a form of cell division in which the daughter cells are genetically identical to the parent cell.
