How does pregnancy begin?

A. Differentiation
B. Fertilization
C. Deviation
D. Contraction

Answers

Answer 1
B Fertilization Answer Answer Answer Answer
Answer 2
Hello,

The answer is option B Fertilization.

Reason:

The answer is option B because fertilization is when the sperm contacts with the egg which starts the pregnancy. Its not option A because its differentiation is the process of comparing. Its not option C because its the action of departing which has nothing to do with pregnancy. Its also not option D because that is used for shoes, or tires which is the grip it has on a surface.

Which process in the water cycle do plants perform? (2 points)

Answers

Transpiration Is the answer
Transpiration is a process similar to evaporation where liquid water is turned into water vapor by the plants. The roots of the plants absorb the water and push it toward leaves where it is used for photosynthesis. The extra water is moved out of leaves through stomata (very tiny openings on leaves) as water vapor.

The method by which lymph is pushed through the lymph vessels is via

Answers

contraction of skeletal muscles against the lymph vessel

The lymph usually move in the body in its own vessel and travels from the interstitial spaces to the subclavian veins at the neck area. The lymphatic system does not have a heart to pump and move the fluid. The movement of lymph depends on the movements of the muscles and joints in the body. In this mechanism upward movement is possible. It will move towards the neck where it will be filtered and will go again into the subclavian veins.

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.

Answers

Think it’s implantation :)

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

Answers

Answer:

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

Answers

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.

Final answer:

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.

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.

Answers

Would just be 860/420 which is ≈ 2W

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.

the answer you are looking for is B.

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.

A nurse is caring for a client who is three hours post op from open abdominal surgery. during routine assessment, the nurse notes the previously stable client now appears anxious, apprehensive, and has a blood pressure of 90/56. what does the nurse consider is the most likely cause of the client's change in condition?

Answers

Anxious and apprehensive are signs that the patient doesn't have enough blood to his brain. The cause probably is the low blood pressure. 
Open abdominal surgery is a major surgery so it should have a high risk of bleeding. Bleeding in abdominal space is dangerous because it was not visible and space is massive. The source could be a rupture of a blood vessel or broken stitch of the surgical wound. 
Then, the most likely cause for the sudden blood pressure drop in this patient would be massive bleeding.

Where is the radius located in reference to the ulna?

Answers

The anatomical position is defined to be the body standing upright with face and torso and feet directed forward and arms around 45 degrees away from the torso with palms facing forward. This is a standard reference in human anatomy, especially in describing body part relations (i.e. the 5th digit of the hand is medial to the umbilicus, etc.). The radius, in anatomical position is lateral to the ulna as ulna is closer to the midline.
The ulna and radius are the two bones of the forearm. The radius bone is shorter than the ulna and is prism-shaped long bone. The radius is a more lateral and slightly shorter of the two forearm bones. It is found on the thumb side of the forearm and rotates to allow the hand to pivot at the wrist. It pivots around the ulna to produce movement at the proximal and distal radio-ulnar.
