Answer:
Explain:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones

Which day had the highest relative humidity ?
1. What controls how the anatomical structures of an organism develop?
In a biological reaction involving an enzyme, what does the substrate bind to? the active site of another substrate the inactive site of an enzyme the inactive site of another substrate the active site of an enzyme
Answer: The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). ... Thanks to these amino acids, an enzyme's active site is uniquely suited to bind to a particular target—the enzyme's substrate or substrates—and help them undergo a chemical reaction. To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. ... The products then leave the active site of the enzyme.
Explanation:
Answer:
the active site of an enzyme

I dont understand what they are asking please help!!
Answer:
"Phenotype" would mean the two letter combination of traits that make up this trait. For example, heterozygous would be something like "Cc", with the "C" representing a dominant trait and "b" representing a recessive trait.
In this case, the answer would look something like "CC", though I'm not sure the exact letters this question is using. Good luck!
Three functions of the eye help!!!!!
Explanation:
The eye receives oxygen through the aqueous. Its function is to nourish the cornea, iris, and lens by carrying nutrients, it removes waste products excreted from the lens, and maintain intraocular pressure and thus maintains the shape of the eye. This gives the eye its shape. It must be clear to function properly.
Answer:
These layers lie flat against each other and form the eyeball.
The outer layer of the eyeball is a tough, white, opaque membrane called the sclera (the white of the eye). ...
The middle layer is the choroid. ...
The inner layer is the retina, which lines the back two-thirds of the eyeball.

Explanation:
You are part of a small group of humans rocketed at “warp speed” to Planet X, without any books, weapons, or technology. Planet X has no ozone layer to protect its surface from cancer-causing ultraviolet radiation, but native plants and animals have evolved to live safely there. Below the surface, the planet has a network of underground tunnels, just a meter high, which are inhabited by carnivorous predators.
Write 3 paragraphs using the vocabulary words we discussed today in class about how descendants of the group of humans would look and act after evolving for 100,000 years on Planet X.
Use these vocabulary words:
• Evolution
• Mutation
• Non-random Mating
• Gene Flow
• Genetic Drift

Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected?
The accidental introduction of invasive species of plants and animals often
causes severe problems in the ecosystem where they are introduced. One such
example is in Texas. The Rasberry crazy ant (Nylanderia pubens) which is thought
to have arrived in 2002 from South America. This ant species is known to attack
livestock, displace existing species, and damage electrical equipment. N pubens
consumes "honeydew," a sugary liquid substance secreted as a waste product by
aphids, which suck the sap out of plants.
Which of the following statements best explains the impact that N. pubens has
on its environment?
Answer: N. pubens has found a place within the existing food web in its new environment.
Explanation:
The statement that best explains the impact that N. pubens has on its environment is that "N. pubens has found a place within the existing food web in its new environment".
From the information given, it's stated that the Rasberry crazy ant (Nylanderia pubens) was accidentally introduced in Texas and it attacks livestock, displace existing species, and damage electrical equipment.
It's further stated that it consumes "honeydew," a sugary liquid substance secreted as a waste product by aphids, which suck the sap out of plants.
This shows that it has found a place within the existing food web in its new environment.
What conclusion can you make regarding how humans affect biodiversity? Is evidence from the graph to support your answer
Answer:
Decrease population of staghorn coral and spotlight parrot fish.
Explanation:
Humans greatly affects biodiversity by decreasing the population of most of the organisms due to its activities. Human activities causes pollution in the environment as well as disturbed the habitats of many organisms that leads to decrease in their population. Humans activities releases carbondioxide gas in large concentration that will leads to the increase of pH of the ocean water which adversely affected the population of many marine animals such as staghorn coral and spotlight parrot fish etc so that's why we can say that human activities adversely affected biodiversity.

Answer:
Warning, it is advised if pregnant that you do not consume alcohol as it can cause discomfort or risk of injuring the foetus.
Explanation:
In your own words, give a brief overview of the process of photosynthesis. Include where each phase place within a plant cell.
Answer:
Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.
The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.
The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.
The following are all concepts of natural selection EXCEPT: *
1. Variations can be inherited.
2. A limited number of individuals born will survive to adulthood.
3. There is a struggle for existence among offspring of the same species.
4. All organisms of a species will survive.
Answer:
2 A limited number of individuals born will survive to adulthood.
Explanation:
Answer:
4. All organisms of a species will survive
Explanation:
4 is the complete opposite of natural selection.
Natural selection basically says that certain members of the species will die off and the more fit ones will survive and produce stronger, better-adapted offspring.

How do you're muscles & skeleton work together?
The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape. The muscles of the muscular system attach to these bones, pulling on them to allow for movement of the body.
An animal that does not have the traits to adapt to its surroundings will?
Explanation: If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered, or extinct. Under an evolutionary phenomenon called relaxed selection, traits that were advantageous in one time and place become obsolete in another. Traits that aren't actively maintained by natural selection tend to become smaller or less functional over time, studies suggest.
