Answer:
c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.
Explanation:
Earth’s tilted cause the four seasons in different parts of earth. In summer, the surface of earth is present directly to the sun causes high temperature of that region while on the other hand, the same region experience cold temperature in winter due to tilt of the earth which does not allow the solar radiation comes directly to that region of the earth that leads to cold temperature.

What does it mean if elements are in the same period
Enter text here
Answer:
--> 12.011 is the relative atomic mass number of carbon.
--> elements in the same group have the same number of electrons in their outermost shells
--> elements in the same period have the same number of electron shells.
Explanation:
An element is a pure chemical substance that contains the same type of atoms which cannot be broken down into smaller substances by any chemical reaction. Example of an element is Carbon, hydrogen, Helium, Nitrogen.
Carbon has the relative atomic mass number of 12.011 in the periodic table. This is as a result of carbon having six protons, six neurons and six electrons. Carbon being an element that has isotopes, the number of decimal seen is its relative mass compared to 1/12 the mass of one atom of carbon-12.
Periodic table shows the properties of elements that vary in a regular manner. The elements in the same GROUP have the same number of electrons in their outermost shells. Electrons are arranged in shells which forms the outermost part of an atom around the atomic nucleus. Electron are arranged in shells called K,L,M,N outward from the nucleus with maximum number 2,8,18,32 respectively. For example, atoms in group 1 include hydrogen, Lithium, Sodium and potassium. When arranged in shells, they all have the same number remaining in their outermost shell which is 1. This makes them to have similar chemical properties.
Elements in the same period have the same number of electron shells. Example of elements in the same period include sodium, magnesium, aluminium silicon, phosphorus. When their atoms are arranged in shells, they have the same number of shells irrespective of the atomic number.
2. Why was the Land between the Rivers such an important region for the development of early
human civilization?
A. It contained a lot of people.
B. It contained rivers.
C. It was located in the Fertile Crescent.
D. It was an arid area surrounded by mountains.
Answer:

List 2 regulations for pesticides.
During a football game, you are starting to feel cold, your body starts to shiver. What is the path of communication between your nervous system and endocrine system to help your body stay warm?
Multiple choice question.
A)
Your sensory receptors in the nervous system recognize the external change in the environment and send a signal through the somatic nervous system to your muscles and glands and tell them to start shivering.
B)
Your sensory receptors in the nervous system are blocked due to the lower temperatures so the internal receptors know that something must be wrong. It works with the endocrine system to maintain homeostasis.
C)
Your sensory receptors in the nervous system recognize the external change in the environment and immediately send a signal through the autonomic nervous system to a gland that gradually communicates your internal body temperature is also changing. Both systems work together to maintain homeostasis.
D)
Your sensory receptors in the nervous system recognize the external change in the environment and send a signal through the autonomic nervous system to your muscles and tell them to start shivering. The endocrine system is useless.
E)
Your sensory receptors in the nervous system can’t recognize the external change in the environment and rely on the endocrine system to help them know when to communicate with the muscles to shiver.
Answer:
C)
Your sensory receptors in the nervous system recognize the external change in the environment and immediately send a signal through the autonomic nervous system to a gland that gradually communicates your internal body temperature is also changing. Both systems work together to maintain homeostasis
Explanation:
The answer basically gives you an explanation, but here is mine:
The nervous system works heavily with the brain by sending signals through nerves. The endocrine system secrete chemicals for wide ranges of things, but it does this with a message that is relayed the nervous system. Since in this problem the temperature is decreasing, then the nervous system will send a message to the brain and then the message gets sent to whatever system is needed to adapt to the temperature decrease which in this case it the endocrine.
This was pretty lengthy, but I hope it helps :)

Answer:
Explanation:
When you have had the chickenpox virus once, the Antigen . Presenting . Cells (A.P.C) have the ability to produce antibodies that latch onto the chickenpox pathogen. This then attracts other white blood cells to perform phagocytosis.
A chicken pox vaccination will usually protect a person from chickenpox for the rest of their lives due to the white blood cells being able to tell when the pathogen of chickenpox has entered the body. This vaccine is essentially a dead form of chickenpox.

List 3 of your characteristics that are caused by your genetic information
Answer:
Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms. For example, blood type can be A, B, AB or O.
So the answers must be from you like what's your blood type, eye colour and if you don't know your blood type you can ask your parents

The human body does not constantly lose water through
a. respiration
b. digestion
c. perspiration
d. urination
Please select the best answer from the choices provided
A
B
C
D
The human body does not constantly lose water through Respiration.
What is respiration?Respiration is the process by which the body obtains oxygen from the air we breathe and uses it to produce energy through cellular respiration. Respiration involves the movement of air in and out of the lungs, where oxygen is exchanged with carbon dioxide. The oxygen is then transported to cells throughout the body where it is used to support cellular respiration. Respiration is a critical function that supports the body's energy needs and helps maintain overall health and well-being.
Digestion, perspiration, and urination are all processes that result in a constant loss of water from the body.

DNA damage suffered by a cell DNA damage suffered by a cell a lymphocyte responding to an active infection a lymphocyte responding to an , active, infection differentiation of a stem cell into a specialized cell differentiation of a stem cell into a specialized cell removal of certain tissues during embryonic development removal of certain tissues during embryonic development
Answer:
DNA damage suffered by a cellA lymphocyte responding to an active infectionRemoval of certain tissues during embryonic developmentExplanation:
Apoptosis is an ordered and programmed process of cellular death. It responds to the organism´s needs during development and the whole life. It is a normal and necessary process.
There are different reasons and moments in life where apoptosis takes place.
Embryogenesis: During embryo development, some tissues need to be removed to continue to the next development stage. A typical example is the hand´s tissues. During the early stages, the hand looks like a la plate. With the pass of days, tissues between the fingers are removed by apoptosis. Adulthood: Adults also go through the process of apoptosis. In cases where the person develops abnormal cells with damaged genetic material, they are subjected to apoptosis.Another scenario is a cell with an infectious agent, such as a virus, affecting the cell´s and the organisms´ proper functioning. When the active infection is affecting the cell or the tissues, these cells also suffer apoptosis.

Acid deposition kills things ___.
A. very slowly
B. within minutes
C. within hours
D. at an average rate
Acid deposition kills things at an average rate.
What is Acid deposition?When sulfur dioxide (SO2) and nitrogen oxides (NOX) are released into the atmosphere and carried by wind and air currents, acid rain is the result.
Nitric and sulfuric acids are created when the SO2 and NOX react with water, oxygen, and other substances. Then, before hitting the ground, they combine with water and other substances.
The majority of the SO2 and NOX that contribute to acid rain originates from burning fossil fuels, however a tiny amount comes from natural sources like volcanoes.
Therefore, Acid deposition kills things at an average rate.
