Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.
What is Cellular transport?
Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.
The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.

Essay on atoms 70 words
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.

Provide evidence to support the claim that viruses fall on the border between living and nonliving.
Answer:
Just like living organisms, viruses use genetic material such as DNA or RNA, but unlike living things, they cannot reproduce using mitosis, binary fission or meiosis. Instead, they simply insert the genetic material into a living cell and then replicate their genetic material along with the cell's in order to create more viruses.

In the United States, alcoholic beverages that are sold in stores display a government warning stating that pregnant women should not drink alcoholic beverages. This is because
it prevents cleavage division from occurring, so a zygote cannot become a blastocyst.
if a woman drinks alcohol while she is pregnant, she may not be able to ovulate again after childbirth.
studies have proven that alcohol consumption causes long-lasting disorders in the fetus.
the science of chemistry has shown that alcohol is a reactive substance that may interfere with the mother’s food digestion.
Answer:
It should be "studies have proven that alcohol consumption causes long-lasting disorders in the fetus."
Explanation:
because everything the mother eats enters the child's body alchoholcan cause problems as if th e child were aready born and drinking.

According to the Cell Theory, what is NOT one of the three main tenants?
1. viruses - which are not alive - not made of cells
2. The cell is the smallest living unit in all organisms
3. All living things are made of cells
4. All cells come from other pre-existing cells
Which of the following is NOT a characteristic of all living things?
Ability to reproduce
Ability to move
O Growth and development
Homeostasis
Answer:
homeostatis
Explanation:
The answer should be homeostatis. Organisms can not do this.
Answer:
Ability to move
Explanation:
All organism species have the ability to reproduce, grow and develop, and maintain homeostasis (for example, sweating). Not all organisms can move, however. Cacti, for instance, are stiff and do not move on their own, yet are still alive.

tertiary consumers.
B) They are caten by secondary consumers.
C) They contain the most biomass out of all of the
trophievels.
D) They are the largest trophic level.
E) This level of the food chain has the highest
amount of diversity.
They attract secondary consumers, this applies to the tertiary consumers of the ecosystem.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are interconnected through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into the plant tissue.
The term "ecosystem" was first used in 1935 in a publication by British environmentalist Arthur Tansley. The term was coined by Arthur Roy Clapham, who coined the word at Tansley's request.
The main ecosystem types are forest, desert, rainforest, grassland, tundra, savanna, and mountain ecosystems.

Define the term hominin.
Answer:
a primate of a taxonomic tribe ( Hominini ), which comprises those species regarded as human, directly ancestral to humans, or very closely related to humans.
I hope it helps
Thank U
[tex]\red{Answer:-}[/tex]
✭The Hominini, or hominins, form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan (Chimpanzees and Bonobos), but excludes the genus Gorilla (gorillas).
✭The term was originally introduced by John Edward Gray (1824), long before any details on the speciation of Pan and Homo were known. Gray's tribe Hominini by definition includes both Pan and Homo. This definition is still adhered to in the proposal by Mann and Weiss (1996), which divides Hominini into three subtribes, Panina (containing Pan), Hominina ("homininans", containing Homo "humans"), and Australopithecina (containing several extinct "australopithecine" genera).

b) How does the thermal energy of solid water change as it melts?
Answer:
Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!
