Answer:
Statements A and B.
Explanation:
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
Why do geologists think Earth's core contains mostly iron?
A. The crust contains a mixture of iron and silicon.
B. The crust contains no nickel.
C. Other orbiting bodies contain more iron than Earth's crust does.
O D. The moon's crust contains far less iron than Earth's crust.
Answer:
It should be D
Explanation:
I hope this helps! Let me know if I am wrong.
The geologists think Earth's core contains mostly iron is to be considered as the option c. Other orbiting bodies.
Reason for thinking of geologists:Here the thinking should be earth core that comprises iron since the earth should contain the powerful magnetic field that is due to the molten iron in the core.
Also, there should be constant movement leads to the electrical current.
hence, the option c is correct.

A converging lens can be defined as ___
A) a lens that causes parallel light rays to bounce off the surface
B) a lens that causes parallel light rays to separate from each other
C) a lens that allows parallel light rays to pass without changing directions
And D) a lens that causes parallel light rays to focus at a specific location
Answer:
D) a lens that causes parallel light rays to focus at a specific location
Explanation:
Lexically, to CONVERGE means to MEET. Converging lens, also known as double convex lens is that which causes rays of parallel light to become focused at a point i.e meet at a specific location.
The parallel rays of light come from different direction but the converging lens is structurally suited to cause them to converge or focus at a point.

Which piece of observation would support your explanation that the chameleon use a physical characteristic adaptation to survive in its environment?
A) A change in skin color
B) An increase in number of eggs
C) Carrying eggs in their mouth
D) Living in large groups
Answer:
A Change its skin
Explanation:
the Chameleon changes it skin to intimidate predators or to blend into an enviroment. And since changing the color of your skin is physical its A!
Adaptations are the characteristical behavior and physical changes. A change in skin color is the physical adaptation of a chameleon to survive in the environment. Thus, option A is correct.
What is adaptation?
Adaptations are the modifications and transformations a species adapts over time in their physical appearances in response to the stimuli that allow them to survive in the surroundings.
Physical adaptation includes the structural change in the shape, the color of the body, fur, and thickness and thinness of the body fur. A change in the skin color of a chameleon allows it to blend into its environment hence, protecting it from predators.
Therefore, the change in the skin color of a chameleon is a physical adaptation.

1. Which of the following is NOT a key factor important to the development of human society?
A. Access to clean water
B. Access to fertile soil
C. Access to cities
D. Access to natural resources
Access to cities is not a key factor important to the development of human society, but clean water, fertile soil, and Access to natural resources all are needed, hence option C is correct.
What are factors important to the development of human society?The preagricultural (hunting and gathering) stage, the agricultural stage, and the industrial stage are thus the at least three primary stages of societal evolution or civilizations.
Clean water is essential to our way of life because it creates a habitat for species and places to fish, paddle, surf, and swim. Our economy is reliant on clean water to operate and thrive. This includes industries like manufacturing, agriculture, tourism, recreation, and energy generation.
They support tax revenue, income, and the fight against poverty. Natural resource-related industries generate employment and frequently form the backbone of poorer towns' economies.
Therefore, natural resources are fundamentally important, so they must be managed responsibly.

Which best explains why the rate of a reaction decreases at significantly higher temperatures?
A. The activation energy increases.
B. The shape of the enzyme changes.
C. The enzyme-substrate complex forms.
D. The bonds between substrates are broken.
Answer:
B
Explanation:
At significantly higher temperatures, the rate of an enzyme-catalyzed reaction decreases because the shape of the enzyme changes at high temperatures. Enzymes are proteinous in nature, and as such, are generally sensitive to high temperatures.
They simply become denatured by high temperatures. In other words, they lose their original shape and their catalyzing abilities as the temperature gets progressively high during the course of reactions, thus, decreasing the rate of a reaction.
The correct option is, therefore, B.
Which of the following best describes the division of cytoplasm and the cell membrane?
a:Cytokinesis

If a couple has four daughters the % chance of their next child being a daughter is
Answer:
50% chance
Explanation:
Humans have two sex chromosomes, the X chromosome and the Y chromosome. Males inherit both X and a Y chromosome, while females inherit two X chromosomes. Thus, the sex of the child is determined by the sex chromosome carried by the male gamete (i.e., X or Y chromosome) which fuses with the egg cell (always containing an X chromosome). In consequence, the chance of having a sperm containing an X chromosome (i.e., the chance of having a girl) is an independent event of previous fertilization events (which led to the formation of 4 different female zygotes), thereby the probability will be 50%.
Which of the following is NOT in part of the natural selection process?
A. a species produces more offspring than can survive
B. an organism adapts to their environment causing variation
C. individuals competing with each other
D. fossils being formed
Answer:
the selection that is not a natural selection process is D: fossils being formed
Answer:
D. Fossils being formed
Explanation:
In the natural selection process, the point is that the animal which is best adapted to the environment survives, so their offspring can survive and produce more offspring that adapts. This is because organisms need to adapt to their environment to survive. Without natural selection, most animals would be too weak to live in their own habitat.
So when we see the answer choices, we have to ask if the species could continue to live and adapt.
A- the species produces more offspring that can survive. Yes, the species can continue to live and adapt.
B- an organism adapts to their environment. Yes, the species can continue to live and adapt.
C- individuals competing with each other. Yes, the better species will win, and continue to live and adapt
D- fossils being formed. No, this has nothing to do with the process of living and adapting. It is in fact the opposite, since it relates to the species dying.
So the answer is D

Explanation:
.When animals breathe, they take in oxygen and give off carbon dioxide. How is photosynthesis like or unlike this process?
Once they have carbon dioxide and water, they can use solar energy to create food. Another gas called oxygen is a by-product of the production of plant nourishment. The leaves emit this oxygen into the atmosphere.
What animals breathe, take in oxygen give carbon dioxide?The act of breathing in oxygen and exhaling carbon dioxide is generally referred to as respiration. The phrase is more precisely used to describe the chemical process that organisms undertake to extract energy from food, a process that normally entails the inhalation of oxygen and exhalation of carbon dioxide.
Therefore, One of the first concepts covered in biology class is that, whereas plants absorb CO2 throughout the day and release oxygen, animals breathe in oxygen and exhale CO2. Plants use the energy from sunlight to transform CO2 and water into sugar and oxygen through a process known as “photosynthesis.”

2. Just as in humans, systems interact in plants to maintain homeostasis and accomplish the functions of transport, reproduction, and response. What are some examples of plant processes that involve an interaction between stems, roots, and leaves?
Answer:
osmosis
Explanation:
plants use osmosis whic is moving water though a semipermial membrane to draw up water. It moves from places of high conetartions of water (dirt) has to is less water (roots). When it does this the plant mains homeostasis by getting water up useing their xylem (tubes in stems) to the leaves.
Plants use osmosis which is moving water though a semipermial membrane to draw up water.
What do you mean by osmosis?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential to a region of low water potential.
Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.
The rate of osmosis always depends on the concentration of solute. The process is illustrated by comparing an environmental or external solution to the internal concentration found in the body.
