PLEASE HELP!!! A mutation occurred in DNA of a globular enzyme. If the leucine amino acids were found within the active site of the enzyme, describe the effect this change is likely to have on enzymatic function
Answer: See below
Explanation:
It may alter the function of the enzyme and may lose its original structure. Leucine is a hydrophobic amino acid that must be buried within the globular enzyme. If it were found on the active site, it may no longer recognize the substrate and may change the shape of the cell in a way that it will not encounter a water molecule
Major organs form and cells continue to divide in the __________ stage. A. Embryo B. Fetus C. Blastocyst D. Zygote Please select the best answer from the choices provided. A B C D.
The prenatal is the stage of the development of the foetus from the fertilized cells towards the whole organism. In the embryo stage, the cells divide and the organs are formed.
What are the stages of prenatal division?In the embryo stage of the foetus development the formation of the cells and their division occurs, it is the early stage of the development where the multicellular diploid organism results in the formation of the distinct organs with specialized functions.
Blastocysts are the early group of cells formed after zygote formation and is important for the implantation in the uterus lining.
A zygote is the immediate result of egg and sperm fusion. This cell is the earliest cell that is diploid and is formed just after fertilization.
Therefore, option A. embryo is the stage in which the formation of the organs occurs.

When we make inferences about one population proportion, what assumptions do we need to make?.
Answer:
It is necessary to make the following assumptions when making inferences about a group of people based on a sample of subjects drawn from that group:
Data is quantitative in nature.A sample size of 30 or more is required.The data set must consist of a simple random sample.A Normal Distribution must be present in the data.The data must come from a sample that isn't all the same size so that it can be generalized well.
The sample size must be at least 30 or more, according to the central limit theorem.
Mean and standard deviation are two examples of quantitative data from which statistical conclusions can be drawn.
To avoid bias, the sample size should be increased rather than the distribution skewed.

Which organism would the researchers most likely predict to be the most distantly related to eukaryotes?.
Answer:
Organism I (circular chromosomes)
Explanation:
I can eliminate organisms II, III, and IV because these organisms have linear chromosomes therefore making it the most closely related to eukaryotes because they consist of linear chromosomes. My only other choice would be organism I, and since it has circular chromosomes we can conclude that this is the most distantly related to eukaryotes.
The organism I is most likely predicted to be the most distantly related to eukaryotes by the researchers.
What do you mean by Eukaryotes?Eukaryotes may be defined as any cell or organism that possesses a clearly defined nucleus and other cell organelles.
Except for organism I, all other organisms possess a linear set of genetic material, while organism I possess a circular set of chromosomes which is closely related to prokaryotes.
Therefore, the organism I is most likely predicted to be the most distantly related to eukaryotes by the researchers.

A.homeostasis
B.osmosis
C.translation
D.diffusion
Answer:
homeostasis i believe, i dont know
Evaporation happens when a liquid turns into a gas. When you sweat, the liquid on your skin evaporates into the atmosphere to cool you off. When you see a dog panting on a hot day, they are actually increasing evaporation from their tongue and mouth to cool off. Conduction transfers heat through direct contact.

Why does assortment of genes take place in meiosis 1.
Answer:
During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random. This means that all of the maternal chromosomes will not be separated into one cell, while the all paternal chromosomes are separated into another.

A population of trout in a lake has significantly declined over the past year. The main source of food for the fish in this lake are aquatic insects. Due to poor climate conditions, there are significantly fewer insects and thus, not enough food to sustain the population of trout in the lake. Trout is a food supply for larger fish in the lake and without enough trout, other fish are negatively impacted in the lake. What is the problem?
a. Trout population has increased
b. Insect population has increased
c. Insect population has decreased
d. Larger fish population has increased
The decline in the overall population of trout and larger fish is because the Insect population has decreased.
What is a population?A population is a group of organisms of the same species living in the same habitat.

Which two strategies can a rattlesnake use to conserve energy and regulate its body temperature
Answer:
Many snakes prefer to move around during the day, when they can alternately bask in the sun's heat and slither into shadows to regulate their body temperatures. As cold-blooded animals, or ectotherms, snakes rely on the environment to keep their bodies at optimum operating temperatures.
Explanation:
The two strategies that a rattlesnake use to conserve energy and regulate body temperature are- 1.) Snake can move into the shade 2.) It can sweat to evaporate the water off the skin to lower the temperature. Options A and D are correct.
Behavioral thermoregulation- Rattlesnakes are ectothermic. This means that their body temperature is mainly regulated by the environment they live in. Rattlesnakes exhibit thermoregulatory behaviors to conserve energy and regulate body temperature.
Rattlesnakes enter torpor when resources are limited or the environment is unfavorable. During torpor, the rattlesnake’s metabolic rate slows down, allowing it to conserve energy. This process slows down the snake’s physiological processes and lowers its body temperature.
This process can occur during hibernation in cold climates or when the environment is unfavorable, such as during drought or when there is a lack of food. This allows the rattlesnakes to adapt to challenging conditions with minimal energy expenditure.
Therefore, the correct options are options A and D.
