How does the cell membrane help maintain health in life
Answer:
The cell membrane controls the substances that enter and exit the cell
Explanation:
The cell membrane defines the boundaries of the cell, separating the internal components from the external environment.
The membrane is a semi-permeable barrier that lets some substances in and out, but not others.
Therefore, the cell membrane controls many of the activities of the cell. As a result, it is crucial to maintain the normal functioning of the organism

Atmospheric Layer Describe what happens to the temperature as altitude increases. Be sure to note specific altitudes where abrupt changes occur and how each layer is heated. Troposphere Stratosphere Mesosphere Thermosphere Exosphere Ionosphere
Answer:
Kindly Check explanation section.
Explanation:
The atmosphere has zones and each zones has it characteristics with respect to atmospheric conditions such as temperature, pressure and humidity.
So, the question only asked us to compare or show the temperature describe what happens to the temperature as altitude increases in each region of the atmosphere.
(1). Troposphere: the region known as troposphere in the atmosphere has a lower Temperature. The troposphere is a region in which the earth gets its radiation and re-radiates its electromagnetic radiation to give heat which later cools down.
(2). Stratosphere: what occurs in the region known as the stratosphere in the atmosphere is that there will be absorption of UV by the O3 layer which will in turn INCREASES THE TEMPERATURE.
(c). The Mesosphere: in this region of the atmosphere the temperature DECREASES.
(d). Thermosphere: there is surely an INCREASE IN TEMPERATURE in this region because of solar radiation.

A student states that exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time. An experiment is carried out to test this hypothesis. One group of ten students sits quietly before squeezing a clothespin as many times as possible during a one-minute interval. A second group of ten students does 25 jumping jacks before squeezing a clothespin as many times as possible during a one-minute interval. What is the independent variable?
Answer:
EXERCISE
Explanation:
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.
In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).
The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.

Does respiration expend more energy than photosynthesis?
Answer:
Explanation:
Photosynthesis vs Cellular Respiration Photosynthesis and cellular respiration are two basic metabolic processes occurring in the energy conversion of ecosystems. During photosynthesis, carbon dioxide and water are used in the synthesis of organic compounds with the aid of sunlight. This organic compounds can be used by cells as food. During cellular respiration, energy in the form of ATP is produced by breaking down food. The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

The role of the electron transport chain in the process of photosynthesis will be carrying electrons from photosystem 1, to photosystem to NADP. The correct option is C.
What is electron transport chain?An electron transport chain is a collection of protein complexes and certain other compounds that donate electrons from electron donors to electron acceptors via redox reactions and couple this electron transfer with the transfer of protons across a membrane.
Photosystems I and II are protein complexes found in the thylakoid membrane.
Their function is to capture high energy electrons from chlorophyll and pass them on to a series of electron carriers before splitting water to form oxygen and hydrogen ions and producing NADPH.
Electron transport contributes to the formation of a proton gradient, which drives ATP production and also stores energy in the reduced coenzyme NADPH.
This energy is used to power the Calvin Cycle, which produces sugar and other carbohydrates.
Thus, the correct option is C.

about 300 million years ago
about 4.5 billion years ago
The scientists believe the continents formed Pangaea about 300 million years ago. The correct option is C.
What is Pangaea?According to National Geographic, the Pangaea theory proposed that the tectonic plates that make up the planet's external crust glided over the inner layers until they consolidated as a landmass encircled by a huge ocean called Panthalassa.
After a while, the Angaran continent near the North Pole began to move south and combined with the northern part of the expanding Euramerican continent, forming the Pangea supercontinent. This process was completed approximately 300 million years ago.
Alfred Wegener observed the same thing in 1912 and proposed that the continents were once scaled down into a single protocontinent known as Pangaea.

Endoplasmic reticulum Golgi bodiesRibosomesExplanation:
ENDOPLASMIC RETICULUM - The endoplasmic reticulum ( ER) is a broad, dynamic structure that serves many cell functions, including the storage of calcium, protein synthesis and metabolism of lipids. Separate regions, consisting of tubules, sheets and the nuclear envelope, perform the diverse functions of the ER.GOLGI BODIES -: A membrane bound organelle found in most cells is the golgi apparatus. Before secretion, it is responsible for packaging proteins into vesicles and thus plays a key role in the secretory pathway.RIBOSOMES -: The organelles which aid in protein synthesis are ribosomes. For many cell activities, protein is necessary, such as damage repair and other chemical processes.A ribosome is composed of two subunits:
the small ribosomal subunits- these read the mRNA. The large ribosomal subunits - form amino acid polypeptide chains.Hence , the labelled diagram of eukaryotic cell is attached below.
