Answer:
The enzyme will no longer be able to catalyze the reaction with the substrate
Explanation:
Enzymes usually have a very specific structure than holds the substrate molecules, facilitating the optimal environment for the reaction to proceed. This reduces the activation energy required to start the reaction.
If the shape changes, the substrate molecule will no longer properly fit. Therefore, the enzyme will not be able to catalyze the reaction.

A cell has a mutation that disrupts the insulin binding site of the insulin receptor. Based on the information in Figure 2, predict the effect of this mutation on the activity of GSK3. Justify your prediction.
Answers
Answer:
See Explanation
Explanation
If insulin cannot bind to the insulin receptor, then GSK3 will not be inhibited, nor will it be able to inhibit glycogen synthase as the activity of kinases such as PKB and GSK3 are dependent on the signal sent out as the response of binding insulin to the receptor. No binding leads to no signal which leads to no activity.

Answers
Answer options:
The nucleus was unable to provide instructions for the other organelles in the cells. The mitochondria were unable to undergo cellular respiration and could not produce energy for the cells to function. The lysosomes were unable to remove waste from the cells. The cell membrane was unable to allow substances to enter and exit the cells.Answer:
The mitochondria were unable to undergo cellular respiration and could not produce energy for the cells to function.Explanation:
Mitochondria are the site of aerobic respiration. This is the process that produces energy in the form of ATP. ATP provides energy for all cellular processes. Without this energy, the cell cannot carry out its functions and will quickly die.
Aerobic respiration requires a good supply of oxygen, which the grasshopper would not have had in a sealed container.

According to the given data It most likely rain on Day 4 98%.
The correct option is D.
Briefing:The relative humidity is typically between 90 and 99 percent when it is raining, but it is rarely greater than 100 percent. Rain happens when water droplets get too large to be maintained in the atmosphere and fall to the ground. Clouds are created when invisible water vapor gas condenses to visible water droplets.
Why is humidity more on rainy days?The water vapour content controls the amount of rainfall during extremely strong downpours, in which all of the water in the atmosphere is frequently soaked out. We are more likely to experience rain when the humidity is higher because water vapor expands at a faster rate.

how many moles of C atoms do you have if you have 1.23 x 10^24 atoms ?
Answers
Answer:
2.04 moles of C atoms
Explanation:
The number of moles of C atoms can be calculated using Avogadro's number, which is approximately 6.02 x 10^23 atoms per mole.
To find the number of moles of C atoms in 1.23 x 10^24 atoms, we need to divide the number of atoms by Avogadro's number:1.23 x 10^24 atoms / 6.02 x 10^23 atoms/mole = 2.04 moles
Therefore, if you have 1.23 x 10^24 atoms of C, you would have 2.04 moles of C atoms.

In a diploid plant species, the proportion of progeny expected to be tall and produce round fruit is 32%.
In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. The expected percentages of progeny phenotypes are tall oval = 41%, short round = 41%, tall round = 9%, and short oval = 9%.To determine the proportion of progeny expected to be tall and produce round fruit, we need to consider the alleles for each trait. Allele D produces tall plants (dominant) and allele d produces short plants (recessive). Allele R produces round fruit (dominant) and allele r produces oval fruit (recessive).From the given percentages, we can deduce that tall ovals and short ovals combined make up 9%. Since tall oval is 41% and short oval is 9%, the proportion of progeny expected to be tall and produce round fruit is 41% - 9% = 32%.Therefore, the proportion of progeny expected to be tall and produce round fruit is 32%.For more questions on diploid plant

Explanation:
A student is testing isopods’ response to light. Isopods (also known as pill bugs or sow bugs) are crustaceans that breathe through organs that need to be kept moist. The results of the experiment show that the isopods move away from light and gather in dark areas as soon as they hatch. Select two statements that explain whether this behavior by the isopods is innate or learned and what adaptive advantage this behavior may have.
A. This behavior appears to be innate, because the isopods could not have learned the behavior during the experiment. The animals exhibited this behavior as soon as they were exposed to the light, right after they hatched.
B. This behavior has an adaptive advantage for isopods because dark areas in nature are usually moist. Those isopods that moved to dark, moist areas were more likely to survive and pass the genetic trait to their offspring.
C. This behavior appears to be learned, because the isopods only exhibited this behavior after they were exposed to the light in the experiment.
D. This behavior is artificial and therefore does not have an adaptive advantage for isopods in nature, because those isopods that moved to dark, moist areas would more likely become food for predators and would not survive.
Answers
The behavior of isopods has an adaptive advantage for them because dark areas in nature are usually moist. Those isopods that moved to dark, moist areas were more likely to survive and pass the genetic trait to their offspring. Thus, the correct option is B.
What is Adaptive advantage?An adaptive advantage is a reproductive advantage in an organism that derives from being well-suited to the specific environment in which it lives. Adaptive advantage is likely to result in an organism that is producing more offspring than those organisms without the adaptive advantage.
Isopods show adaptive advantage because isopods move to dark areas away from light which are usually moist. The isopods that moved to the dark, moist areas were more likely to survive and pass the genetic trait to their offspring than other isopods.

Does the pharynx of human respiratory system have cartilage and epithelium?
Answers
Answer:
There is no cartilage but there is epithelium
Explanation:
The pharynx of the human respiratory system does not contain cartilage.
The pharynx, part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for air and food. The gorge is made up of several regions, each with its own distinctive features.
The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.
These regions also lack cartilage but are lined with stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

is water alive? Why or why not
Answers
Answer:
Neither alive nor dead. Water is non living. We talk about alive or dead only when it comes to living organisms. Living organisms are made of one or more cells and these cells are responsible for their living nature.
Explanation:
No, water is not alive because it does not possess the characteristics of life such as cellular organization, metabolism, growth, reproduction, response to stimuli, and adaptation.
Water is a fundamental substance necessary for life, but it is not considered a living organism. Living organisms are characterized by several key attributes, including the ability to perform cellular functions, respond to stimuli, grow, reproduce, and adapt to their environment. Water, on the other hand, lacks these essential characteristics.
Water is a chemical compound composed of two hydrogen atoms and one oxygen atom (H₂O). It does not have cells or a cellular structure, and it does not exhibit metabolic processes. It does not possess the ability to grow, reproduce, or adapt to changes in its environment. Water molecules do not respond to stimuli or exhibit any form of consciousness or awareness.
While water is crucial for supporting and sustaining life, it is considered a vital component of living organisms rather than a living entity itself. Living organisms rely on water for various physiological processes, such as maintaining hydration, facilitating biochemical reactions, and providing a medium for transport within the body. However, water alone does not possess the necessary characteristics to be classified as a living organism.

If 73% of a population's gene pool is made up of the dominant allele, what percent of the population is homozygous dominant?
Answers
Let $p$ represent the frequency of the dominant allele and $q$ represent the frequency of the recessive allele. According to the Hardy-Weinberg principle, $p+q=1$.
We know that $p=0.73$, so we can solve for $q$:
\begin{align*}
p+q &=1 \\
q &=1-p \\
q &=1-0.73 \\
q &=0.27
\end{align*}
Now we can use the Hardy-Weinberg equation to determine the frequency of homozygous dominant individuals in the population:
\begin{align*}
p^2 + 2pq + q^2 &= 1 \\
p^2 &= (0.73)^2 \\
p^2 &= 0.5329 \\
\end{align*}
Therefore, the frequency of homozygous dominant individuals in the population is $p^2 = 0.5329$, or approximately $53 \%$.
So, about $53 \%$ of the population is homozygous dominant.
