Answer:
One key way by which species evolve over time in response to changes in environmental conditions is adaptation by natural selection acting over generations. Characteristics that aid in effective survival and reproduction in the new environment grow more prevalent, while those that do not become less prevalent.

What are chromosomes?
Answer:Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.
The word "chromosome" is derived from the Greek terms "chroma" and "body" (soma).

Consider this plant cell. The organelles in a plant cell are labeled. Part G is the middle layer of the cell. Which organelle is labeled G?
Answer:
Hi. You didn't show the picture that shows organelle G, but since you showed that organelle is the middle layer of the cell, we can say that it is the plasma membrane.
Explanation:
In general, we can state that the plant cell has three layers, the cell wall, the plasma membrane and the cytoplasm. The cytoplasm is the inner layer, where most of the organelles and the cell nucleus are located. Above the cytoplasm is the plasma membrane, which is semi-permeable and promotes the regulation of the entry and exit of substances from within the cell. Above this membrane is the cell wall, which is an impermeable structure that protects the cell and promotes its rigidity. In this case, we can consider that the middle layer of the cell is the plasma membrane.

Which choice BEST explains why each island in the Galapagos has unique kinds of iguanas?
A. Iguanas prefer a marine environment.
O B. Some iguanas are better swimmers than others.
O C. The species arrived on the islands in different ways.
OD. The species adapted to each island's unique habitat.
The statement that explains each island in the Galapagos has unique kinds of iguanas is that the species adapted to each island's unique habitat. The correct option is D.
What is adaptation?Adaptation is defined in biology as a heritable behavioral, morphological, or physiological trait that has evolved through natural selection and maintains or increases an organism's fitness under a given set of environmental conditions.
To survive, all organisms must adapt to their surroundings. This entails adapting to the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.
The marine iguana is the only lizard in the world that can live and forage at sea, and it is only found in the Galapagos Islands.
There are eleven very similar subspecies found on various islands, with Isabela and Fernandina having the most. The species adapted to the distinct habitats of each island.
Thus, the correct option is D.

Reproduction for dolphins and badgers and people is more complicated because
A. we have to apply for a license before we can reproduce
B. have to find a partner
C. go through the cellular process of MITOSIS to produce sex cells.
Answer:
B. have to find a partner
Explanation:
When two badgers get together and fall in love, a sperm cell from the father which contains a copy of half of his DNA, only half, combines with the egg cell of the mother, which contains half a copy of her DNA. The result is a brand new cell with all the information to divide and grow up into a brand new badger. The new child matures to be similar to our parents, but also unique, because she developed some traits from her mother’s DNA, and some from her father. Her new combination of traits can be passed on to her children, and again.

To determine the density of a rabbit population, one would need to know the number of rabbits and __________. View Available Hint(s) To determine the density of a rabbit population, one would need to know the number of rabbits and __________. their pattern of dispersion the size of the region in which they live the factors that limit population growth for that rabbit population the growth rate of the population the birth rate
Answer:
The growth rate.
Explanation:
To determine the density of a rabbit population, one would need to know the number of rabbits and the growth rate of rabbit's population because both factors allow us to determined the population of rabbit in a specific region. If we know the existing population of rabbits in a particular area as well as the growth rate at which the rabbit population increases so we can find out the density of rabbit population in a specific time period.
What are the phenotypes of an organism?
A. the organism's genes
B. the organism's physical traits
Answer:
A.
Explanation:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
Answer:
A. the organism's genes
Explanation:
The phenotypes of an organism are the genes carried by the organism.
A Russian citizen has illegally obtained a Siberian tiger and is trying to sell the tiger’s fur in the United States. What treaty does this violate?
A.Tiger Treaty
B.Lacey Treaty
C.CITES
D.EPA
Answer:
Cites,
Explanation:
Another Answer on Brainly
The treaty that the Russian citizen violated is CITES or Convention on International Trade in Endangered Species. The treaty was drafted from 1973 in order to protect the over - exploitation of wildlives.
A Russian citizen has illegally obtained a Siberian tiger and is trying to sell the tiger’s fur in the United States, CITES treaty does this violate. Therefore, the correct statement is option C.
What is CITES?CITES, or the Convention on International Trade in Endangered Species of Wild Fauna and Flora, is the treaty that this action would break. Since Siberian tigers are considered an endangered species, the Convention on International Trade in Endangered Species (CITES) regulates international trade in their parts or products.
A violation of CITES regulations is the illegal possession, sale, or transportation of an endangered species or its parts or products, like fur, without the necessary permits or documentation.
The Lacey Act is a US regulation that denies the exchange unlawfully got natural life, plants, and their items, yet refers to a worldwide settlement that oversees the exchange of jeopardized species across borders. The United States Environmental Protection Agency (EPA) is in charge of enforcing environmental laws.
Therefore, the treaty that this action would violate is CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora).

Explain in at least five sentences what you've learned about how
global warming and climate change are impacting our Earth in different regions of the world.
Explanation: I'd first address the issue as a whole and explain the meaning and the general impacts of climate change, then use a variety of different places. For example, global warming causes the ice caps to melt in Antarctica. Then, explain how this has an impact on the environment meaning that polar bears could be in life-threatening situations and possibly even become extinct in the future which has a further impact on other animals in that food chain and ecosystem. This is just one example. You could also explain the unbearable heat in countries nearer the equator, which prevent crops from growing; the sea levels rising; or extreme weather events like huge flooding or heatwaves. It depends what you have learnt about in class, but I'm assuming it would be about this sort of thing.
Answer:
Higher death rates. ...
Dirtier air. ...
Higher wildlife extinction rates. ...
More acidic oceans. ...
Higher sea levels.

"I don't get it. Why do I need to learn about meiosis to understand about variation in a species?" moaned Trina. How would you explain to her what the relationship is between the two?
Answer:
The cell division that halved the no. of chromosomes is the meiosis. The meiosis takes place during formation of gametes (eggs & sperms) in higher organisms. eggs & sperms posses only one chromosomes of each pair of chromosomal set. (2n➡️n).
When these gametes fuse to form the zygite, the chromosomes become n+n➡️2n again.

Answer:
The correct answer is - are found on microtubules in cilia and flagella and cause movement by grabbing and pulling at adjacent microtubule doublets.
Explanation:
Dynein feet or arm is made up of dyneins a family of cytoskeletal motor proteins that present on microtubules in flagella or cilia or both and drives the beating motion of cilia and flagella.
These form the rows of arms or feet inside and outside, associated with the doublet microtubules of motile cilia that produce microtubule sliding to move along. It gets its energy through ATP hydrolysis.
