Answer:
Metals are not macromolecules. So D is the answer.
Metals are not macromolecules whereas proteins and carbohydrates are macromolecules. Macromolecules are essentially polymers, long chains of atomic sub-units called monomers. Long polymers are present in proteins, carbohydrates, and nucleic acids. They are referred to as macromolecules because of their large size and polymeric nature.
There are four significant classes of natural macromolecules that are constantly found and are fundamental for life. Proteins, nucleic acids, carbohydrates, and lipids (or fats) are all examples of these.

what would be a good hypothesis for does caffeine increase the heart rate of an earthworm
A hypothesis is usually an if then because statement, but the answer will differ as there may be multiple hypotheses to use for a single experiment.
If an earthworm had an intake of caffeine, then their heart rate would increase because it would happen the same for humans as well.

How do scientists use ice to study ancient climates
Answer: Ice is very important for studying ancient climates. Ice can preserve the remains of organisms such as a Wholly Mammoth, possibly for hundreds of thousands of years. The details and phenotype of the mammoth such as its fur, can provide evidence of Earth's ancient climate, and where it occurred (which is somewhere that contains ice).

Before mitosis begins, which happens before the nucleus starts dividing?
The DNA replicates.
The cytoplasm separates.
The sister chromatids separate.
The homologous chromosomes cross over.
Answer:
The DNA replicates.
Before mitosis begins, the DNA replicates. During the S phase of interphase, which precedes mitosis, the DNA in the nucleus undergoes replication, resulting in the formation of identical sister chromatids.
This ensures that each daughter cell produced during mitosis receives a complete set of genetic information.
After DNA replication, the cell enters the mitotic phase, during which the nucleus divides and the replicated DNA is distributed to the daughter cells.
The cytoplasm separates during cytokinesis, which occurs after mitosis and is not directly related to events before nucleus division. The separation of sister chromatids occurs during anaphase of mitosis, not before the nucleus starts dividing.
Thus, the process of homologous chromosomes crossing over occurs during meiosis, not mitosis.

10. Define immunity, and distinguish between active and passive immunity. this should be 150 words. I will mark as BRIANILIST. thank you.
Answer:
Immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or another unwanted biological invasion, while having adequate tolerance to avoid allergy and autoimmune diseases. Each part of the immune system has a unique function. Also, the immune system is responsible for down-regulating immune responses against external harmless triggers such as food, or against the bodies' tissue. Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response. And passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally when maternal antibodies are transferred to the fetus through the placenta. Passive immunity refers to the transfer of antibodies from one individual to another.
Vestigial structures, such as hip bones in whales and appendixes
in humans, are those that have little or no function for the
organism. What is the most likely reason for this loss of function
over time?
The organism is undergoing speciation.
The organism is experiencing genetic drift.
The structure was over utilized by the organism.
The structure was not highly beneficial to the organism.
Answer:
A.
Explanation:
Humans used to use the appendix for good bacterial health in the gut. People used to drink dirty water and eat food that had lots of bacteria. The appendix would save them from infection.

Eric has made a terrarium, a closed container with plants in it, and he has put
enough water into it to satisfy the needs of the plants. Does Eric need to add
water to his terrarium again? Why or why not?
Answer:
Yes
Explanation:
The water will be used by the plants sooner or later so their basic metabolic needs can be achieved. Also, the plants will loose their water by transpiration, in order to produce their carbohydrates. Therefore the amount of water will not be enough and has to be replenished.

What might happen to the Burmese python population over time as it reaches or
surpasses its carrying capacity in South Florida? How might other organisms in the
ecosystem be affected? What might happen to the population sizes of various types
of organisms in the Everglades?
Answer:
If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.
Explanation:
If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.
What is carrying capacity?The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.
Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.

a) Embryo develops into the fetus
b) Zygote cell rapidly divides
c) Embryo embeds into uterine wall
d) Zygote travels down the fallopian tube toward the uterus
Storing hormones, smooth and cardiac muscles are the correct answers.
Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.
Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.

Sally thinks that the plants get food from the soil and that plants use their roots to take in the food they need for energy. She is worried that her plant will use up the soil in the Microworld and will run out what it needs for food.

Tanya thinks that plants make their own food using air, water, and light. She thinks that as long as her Microworld is in the sun, the plant will have what it needs for food.
Richard
Richard also thinks that plants make their own food using air, water, and light. However, he is worried that there is not enough water or air in the bottle for his plant and that the plant will run out of what it needs to make food before the end of the project.
