The three adaptations that kangaroo rats must possess to survive in a hot, dry climate are fewer sweat glands, the presence of thin coats, and increased water retention ability.
What do you mean by Adaptation?Adaptation may be defined as the accommodation of organisms to their environment in order to enhance their possibilities of survival in that environment.
Kangaroo rats must live in a hot, dry climate. They have fewer sweat glands because this prevents the loss of excessive fluids outside the body of the kangaroo.
Due to the warm and humid climate of the desert, they have better water retention capability to prevent the condition of excessive thirst.
The presence of a thin coat that is oily. They maintain this coat with hygienic dust or sand which helps them to keep the proper level of oil in the fur and prevents water loss.
Therefore, the three adaptations that kangaroo rats must possess to survive in a hot, dry climate are fewer sweat glands, the presence of thin coats, and increased water retention ability.

Question #1
Which statement about meiosis is true
Answer:
A.
Explanation:
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample 30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample
Answer:
See explanation
Explanation:
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).
Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.
Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.
ammonia stays the same
nitrates decrease
nitrates increase

D. A compound contains many different kinds of elements, whereas an element
contains many different kinds of atoms.
Answer:
C. Elements are made of identical atoms, whereas compounds are made of identical molecules.
Explanation:
Elements are made of identical atoms, whereas compounds are made of identical molecules because elements are made of atoms of only one kind while on the other hand, compounds are the pure substance that is made of molecules that is similar as well as different from one another. Both element and compound are pure substance. Compound can be broken down by chemical means whereas elements can not be broken down.
Which of the following are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes? (Choose all that apply)
•comparison of human behaviors
•carbon dating of fossils
•comparison of blood proteins
•comparison of homologous structures
Answer:
B and D
Explanation:
Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.
The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.
So, option B and D are correct one.
Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct
What is Carbon dating?It is also referred as radiocarbon dating.It is the method used to determine the age of the living organism containing organic( carbon ) based material by using isotopes of carbon which is radioactive.Learn about carbon dating

7. Why is it so unlikely for a girl to get a disorder like Duchenne Muscular Dystrophy
Answer:
Because it takes a very long time and an interesting mindset.
Explanation:
People don't really have an explanation for the things that we do they just suddenly build up inside us
Answer:
This is because the mutated gene responsible for Duchenne is located in the X chromosome. Girls have two X chromosomes, meaning that the body usually inactivates the chromosome that carries the mutation. The female will carry the mutation, but manifest little to no symptoms of the disease.

In what respect is a mycelium and a fruiting body similar?
Both are made of hyphae.
Both are found above the ground.
Both produce reproductive spores.
Both absorb nutrients underground.
Both produce reproductive spores. Therefore, option (C) is correct.
What are reproductive spores?Reproductive spores are specialized structures produced by certain organisms for the purpose of reproduction. Spores are single cells or groups of cells that are capable of developing into new individuals under suitable conditions. They are typically small, lightweight, and highly resistant to environmental conditions, allowing them to disperse over long distances.
Various organisms produce reproductive spores, including fungi, algae, plants (such as mosses and ferns), and some bacteria. These spores serve as a means of reproduction and dispersal, enabling these organisms to colonize new habitats and propagate their species.
Reproductive spores can be produced through different mechanisms, such as asexual or sexual reproduction. In some cases, spores are released into the surrounding environment and can be carried by wind, water, or other organisms, allowing for widespread distribution and colonization.
