How does running affect the human (Homo sapiens) heart rate? And is that affect negative, positive, or insignificant? (Answer Question Below)
What are the Confounding Variables?
Answer: During exercise/running, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps. Generally speaking, your heart beats both faster and stronger to increase cardiac output during exercise. It shows a positive effect. therefore, Physical activity is a confounding factor of the relation between eating frequency and body composition.

Terminal flowers are at the tip of the stem.In a group of pea plants, some individuals have axial flowers and others have terminalflowers. In this group, the gene for the flower position trait has two alleles. The allele F is foraxial flowers, and the allele f is for terminal flowers.A certain pea plant from this group has axial flowers. This plant has one allele for axialflowers and one allele for terminal flowers.Based on this information, what is this pea plant's genotype for the flower position gene?axial flowersFfffterminal flowers
Axial flowers are in the middle of the plant's stem.
Terminal flowers are at the tip of the plant's stem.
The alleles that code for the trait "position of the flower" are F: axial flowers, and, f: terminal flowers.
A pea plant has axial flowers (Phenotype of the plant)
You know that it has one allele for axial flowers, F, and one allele for terminal flowers, f.

The law of _____ suggests that the orbit of planets is not circular but _____. Fill in the blanks: circles triangles ellipses rectangle
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.

a technologist is performing a body fluid analysis on a csf specimen recently received in the laboratory. four csf tubes were sent to the body fluids bench. the tech notices that all four specimens seem moderately blood tinged equally. moderate xanthochromia was also noted. what is the most likely reason for these findings?
The most common cause of xanthochromia, which manifests as a yellow, orange, or pink staining of the CSF, is the breakdown of haemoglobin into oxyhemoglobin, methemoglobin, and bilirubin as a result of RBC lysis.
Xanthochromic CSF: Is it typical?The yellowish staining of a centrifuged CSF specimen's supernatant is known as xanthochromia. It is abnormal and arises from the breakdown pigments oxyhemoglobin, bilirubin, and methemoglobin being released from RBC lysis into the CSF during Xanthochromia therapy. Treatment for xanthochromia entails addressing the underlying cause. If xanthochromia in the CSF indicates that the patient has a subarachnoid haemorrhage, they may have magnetic resonance imaging (MRI), CT angiography, or be sent immediately to the hospital for treatment.
A issue with the central nervous system is suggested by an abnormal protein level in the CSF. A tumour, haemorrhage, nerve irritation, or damage may all be indicated by an elevated protein level.

What is the difference between chromosomes, sister chromatids, non-sister chromatids, separated chromatids?
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.

Using the results to design an additional investigation.B. making a prediction before beginning the investigation.C. systematically recording the results of the investigation.D. choosing data that confirmed the hypothesis of the investigation.
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 chloroplasts of land plants are thought to have been derived according to evolutionary sequence:
cyanobacteria → green algae → land plants
A population's genetic makeup evolves throughout time as a result of the process of evolution. Adaptations made by organisms to their altering surroundings are reflected in evolution, which can lead to changed genes, unique features, and the emergence of new species. Both increases in genetic diversity and shifts in allele frequencies throughout time affect evolutionary processes. Experimentally, the evolutionary process from a "Big Bang" genesis to the protocell and from the advent of the protocell and a diversity of species to Darwin's mental capacity (mind) and society is being reexamined (The Descent of Man). The focus on endogenous ordering is one of studies' most fundamentally revisionary effects.
This concept has had a fresh influence on the notion of Darwinian evolution and has been discovered to apply to the whole sequence. It is well demonstrated in the orderly copolymerization of amino acids. I'll go through a few issues with handling the teaching of contentious themes in this section.

What is the main function of gas exchange ?The waste gas carbon dioxide is exchanged for oxygen at each cell in your body. This waste gas is then transported by your bloodstream back to your lungs, where it is expelled after being eliminated from the bloodstream. Gas exchange, a crucial activity carried out automatically by your lungs and respiratory system, is a fundamental function.
How is gas exchange in the body?While carbon dioxide diffuses into the alveoli and is later breathed out of the body, oxygen diffuses from the alveoli into the capillaries, which carry it out of the lungs and to the rest of the body.

Photosynthesis, What goes in, What goes out, and Where within the cell does it occur?
Photosynthesis is the course where plants utilize sunlight, H20, and CO2 to build O2 and energy in the form of sugar.
In the course of photosynthesis, plants take in CO2 and H20 from the air and soil. Inside the plant cell, the H20 is degenerated or give up electrons, at the same time the CO2 is decreased or avails electrons. This converts the H20 into O2 and the C02 into glucose. The plant then discharges the O2 back into the air, and stock energy within the glucose molecules.
Photosynthesis takes place in small organelles called chloroplasts that stock the energy of sunlight. The chloroplasts contain the chlorophyll which is the primary pigment utilized in photosynthesis. The chloroplasts are enclosed by a double membrane and consist of a third inner membrane called thylakoid membrane that builds long folds within the organelle.
Answer - What goes in - CO2 and H20
What goes out - O2 and sugar
Where it occur - sunlight
The light reactions of photosynthesis takes place in the thylakoid membranes of the chloroplast. The light reactions catch energy from the sunlight which they alter to chemical energy and stock in molecules of NADPH and ATP.
