D. The traits of an offspring are independent from the parents.
S
Answer:
Alleles of a trait separate independently when gametes form.
Explanation:
just answered it
The statement best describes the law of independent assortment is Alleles of a trait separate independently when gametes form.
What is the law of independent assortment?The law of independent assortment says that there are different alleles present for different genes. The allele received by one gene does not affect the allele received by another gene.
Thus, the correct option is C.

nucleotides.
oxyribose and phosphene backbone.
deoxyribose and phosphate backbone.
RNA.
Answer:
deoxyribose and phosphate backbone
Explanation:
The outer part of the DNA double helix contains an alternating sugar (deoxyribose) and phosphate backbone.
The outer part of the DNA double helix contains deoxyribose and phosphate backbone. So, the correct option is (C).
What is DNA?DNA stands for Deoxyribonucleic Acid. It is defined as a polymer that is made up of two polynucleotide chains that are coiled around each other to form a double helix. Polymers contain the genetic instructions for the growth, function, development, and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids.
It contains the biological instructions which make each species unique. DNA with the instructions it contains that is passed from adult organisms to their offspring during reproduction.
One important function of DNA is that it is responsible for a process called protein synthesis, which is the process in which cells make proteins.
Thus, the outer part of the DNA double helix contains deoxyribose and phosphate backbone. So, the correct option is (C).

A) if they have backbones or not
B) if they have brains or not
C) if they walk or fly
D) if they have feathers or fur
Do you think the adaptation of the animal you chose are a result of its environment, genes, or both? Explain
Answer:
The adaptations are result of both the environment and genes. Animal develop adaptive characteristics in response to their environmental challenges. These adaptations help the animals survive in their environment. The animals are more likely to reach reproductive age. So,these adaptive traits are more likely to be passed on to offspring.In the case of cheetahs,tan coloring,conservation of water, and fast legs are traits that help them survive in the savanna. These traits,like all the other characteristics of cheetahs,are genetically passed from parents to offspring.

C necessary for fermentation to take place
D required by all living organisms
E required to break down the ethanol that is produced in muscles
Answer:
the answer is B necessary to replenish glycogen levels

Answer:
A. Kingdom Protista
Explanation:
Kingdom Protista contains mostly unicellular eukaryotes. However, a few are multicellular.
Some protists reproduce sexually using gametes, while others reproduce asexually by binary fission.
Some protists are autotrophic, while others are heterotrophic.
Protists are eukaryotic, as their cells have a nucleus and other membrane-bound organelles.

The human population on Earth is currently growing
O A. exponentially
B. slowly
O C. linearly
Answer: Exponentially
Explanation:
The human population on Earth is currently growing exponentially. Therefore option A is correct.
Exponential growth refers to a pattern where the population increases at an ever-accelerating rate, proportionate to its current size.
This growth is driven by factors like technological advancements, improved healthcare, and higher birth rates.
Over the past few centuries, the human population has experienced significant exponential growth due to advancements in agriculture, medicine, and industrialization, which have allowed for better living conditions and longer life expectancy.
While the rate of growth may fluctuate over time, the overall trend remains exponential.
However, it's essential to consider sustainability and the impact of such growth on resources, the environment, and societal challenges in the future.
Therefore option A exponentially is correct.
