16. use a punnett square to predict the offspring in a cross between a tall pea plant (heterozygous) and a tall pea plant (heterozygous). what is the genotypic ratio of the offspring?
A punnet square to predict the offspring is made below and the genotypic ration will be 25% homozygous tall pea plants, 50% heterozygous tall tea plants, and 25% short pea plants.
Suppose that a tall pea plant has the heterozygous genes Tt hence a punnet square will be formed as follows:
T t
T TT Tt
t Tt tt
According to the punnet square, the genotypic ratio will be 25% homozygous tall pea plants, 50% heterozygous tall tea plants, and 25% short pea plants.
In the scenario above, we know that the dominant allele is the tall one (T) as the heterozygous plants tend to be tall. The effect of the recessive allele is masked by the dominant allele.

How is the renin activated in the alimentary canal
Renin is released into your system when your blood pressure goes too low or your body does not have enough salt. Renin secretion occurs when your arterial arteries' baroreceptors (pressure-sensitive receptors) sense low blood pressure. Your kidneys detect low sodium (salt) levels.
What is the Alimentary Canal?The alimentary canal is mostly known as the conduit via which food enters our bodies and exits through the anus after digestion.
Renin is important in maintaining blood pressure after volume depletion. The role of the renin-angiotensin system in regulating blood pressure levels in persons with normal salt consumption can be assessed with angiotensin-converting enzyme (ACE) inhibitors.

A red blood cell with a low concentration of oxygen will..
A. Absorb more oxygen as it passes by the lungs
B. Pass by the lungs as if nothing happened
C. Diffuse oxygen out into the lungs
A red blood cell with a low concentration of oxygen will absorb more oxygen as it passes by the lungs.
What is red blood cell?
Red blood cells are the most prevalent form of blood cell and the primary way by which vertebrates distribute oxygen to their body tissues through blood flow through the circulatory system. They are also known as red blood corpuscles, haematids, erythroid cells, or erythrocytes.
The kidneys detect an oxygen deficiency in the blood (hypoxia) and respond by secreting a hormone called erythropoietin when low oxygen levels are present (which may be caused by circumstances such as high altitude or low partial pressure of oxygen in the atmosphere) (EPO). The production of RBCs is accelerated by EPO, which increases the RBC count. The higher RBC count helps to make up for the lungs' reduced ability to hold oxygen.
Hence the correct option is a red blood cell with a low concentration of oxygen will absorb more oxygen as it passes by the lungs.

imagine that a toxin is introduced to the body and inhibits the establishment of the proton gradient in the intermembrane space. what would you predict would be the result?
Imagine that a toxin is introduced to the body and inhibits the establishment of the proton gradient in the intermembrane space as a result, ATP synthase would be unable to produce ATP. The correct answer is option(e).
The production of ATP by ATP synthase is dependent on the proton gradient in the intermembrane gap. As a result, the toxin will render it inert. In this situation, oxidative phosphorylation rather than substrate-level phosphorylation is now suppressed.
Pyruvate is a glycolysis byproduct that won't be harmed by a toxin. It is anticipated that the toxin will prevent NADH from being oxidized because it is crucial in creating a proton gradient. The proton gradient is created by the protons created during NADH to NAD+ conversion. NADH is unlikely to be oxidized if the gradient is missing.

Fermentation produces lactate and NAD+ in muscle cells.
The process of producing ATP entirely through glycolysis in the absence of oxygen is known as fermentation. Due to less availability of oxygen, sometimes muscles opt for lactic acid fermentation.
Steps involved in lactic acid fermentation:
Glyceraldehyde 3-phosphate and then 3-Phosphoglyceric acid are the two products of the 6-carbon glucose molecule's decomposition.NADH+H+ is formed as a result of this process.Phosphoenol pyruvic acid is produced by the 3-Phosphoglyceric acid, which then results in Pyruvic acid.Glycolysis results in the formation of two net ATP molecules.With the assistance of the reducing agent NADH+H+, this Pyruvic acid is converted into Lactic acid, which then reoxidizes into NAD+.From two pyruvate/pyruvic acid molecules, this procedure produces two lactate/lactic acid molecules. The enzyme lactate dehydrogenase is required for this reaction to take place.Know more about Fermentation here: https://brainly.com/question/1599790

When solar radiation hits snow and ice, approximately 90% of it is reflected back out to space. As global warming
more snow and ice to melt each summer, the ocean and land that were underneath the ice are exposed at the Earth's
surface. Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the
heat to the atmosphere. This causes more global warming. In this way, melting ice causes more warming and so more ice
melts. This is known as a feedback. According to a recent scientific study that used computer models to predict the
future of Arctic sea ice, there may be no more sea ice left in the Arctic Ocean during summer within the next few
decades.
If 1000 watts of energy per square meter hits an island covered in ice and snow, how much of it is reflected back into
space?
How would the amount of energy reflected back into space differ if all of that ice melted?
DED
90% of the solar light that strikes snow and ice is reflected back into space. Each summer, more snow and ice melt due to global warming, exposing the land and ocean that were previously covered by the ice.
Does ice reflect sunlight back into space?Large amounts of sunlight are reflected off the dazzling surface of sea ice and, more significantly, back into space. Temperatures closer to the poles stay chilly in comparison to the equator because this solar energy "bounces back" and is not absorbed into the ocean.Each summer, more snow and ice melt due to global warming, exposing the land and ocean that were previously covered by the ice. The ocean and land absorb more solar energy because of their darker colors, and they then dissipate the heat into the atmosphere. The result is increased global warming. In this way, as the climate warms more, more ice melts.To learn more about : Global warming
