23. In both plant and animal cells, the cell
membrane
(1) produces enzymes
(2) controls reproduction
(3) is composed of sugars
(4) regulates diffusion
Answer:
the answer is option 1
The Cell membrane regulates diffusion, in plants and animal cells.
What is a Cell Membrane?Every biological cell has a thin membrane that separates it from the rest of the environment this membrane is known as a cell membrane.Cell membranes is made of lipids and proteins.The cell membrane's chemical nature makes it extremely flexible, making it a perfect border for quickly growing and dividing cells.Cell membrane is a semi-permeable membrane.Cell membrane does not produce enzymes.
Hence, the option (1) is incorrect.
Cell membrane cannot control reproduction.
Hence, option (2) is incorrect.
The main constituents of cell membrane is lipids and proteins, not sugars.
Hence, option (3) is incorrect.
Cell membrane regulates diffusion, because the cell membrane contains the semi-permeable membrane which allows only lipids and certain small molecules in the cell.
Hence, option (4) is correct.
Therefore, the Cell membrane regulates diffusion, in both plants and animal cells.

Skim the headings and bold words in this section. Write four steps scientists might take to solve a problem.
Answer:
1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion
The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.
What are hypothesis?A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.
Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.
Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.
The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.
A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.
Thus, by using these steps, scientist can come to an end for the problem.

a. The entire Gorongosa park is 4,000 km². Approximately how large (in km) is the portion of
the park that has been studied?
ASAP PLSS
Answer:
800 km²
Explanation:
If the researchers have studied 20% of the 4000 km² park, to find out how much of the park in km they have studied, all you have to do is find 20% of 4000.
4000 x .20 = 800
800 km² is your answer.
If the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].
What do you mean by the researcher?A researcher may be defined as a kind of person who significantly carries out academic or scientific research in order to find some unrevealed data and information.
According to the question,
The total area of Gorongosa park = Gorongosa park is 4,000 km²
The area which is already studied = 20%.
Now, you have to find the area that is already studied in km. So, you have to calculate the 20% of 4,000 km².
The area which is already studied = 4000 × .20 = 800 [tex]km^2[/tex].
Therefore, if the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].

What causes ocean tides to reach higher up on a shore at certain times of day than at others? A. The moon's gravity and Earth's rotation B. The ocean's conveyor belt and refraction C. Earthquakes and volcanoes O D. Temperature and salinity differences
Answer:
A
Explanation:
I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.
FIND THE INDEPENDENT & DEPENDENT VARIABLE!
- the amount of iron in blood depends on the amount of red meat a person eats.
Answer:
The answer is:
Independent: red meat eaten by a person
Dependent: iron in the blood
Explanation:
A dependent variable has to depend on something else, so in order for a dependent variable to exist or happen, there has to be the independent variable. The independent variable is something that does not need anything else to happen for it to take place. It s independent. Such as, a mother cannot have a child without sperm. The mother have a child is dependent, where the sperm is independent.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
The advice I would give to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.
If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.
If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.

Explanation:
Hoped I helped you out please mark me brainliest!!!
With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.
What is a microscope?A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.
In most cases, the light is focused on the sample by passing it through a condenser.
After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.
The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.
Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

Which body systems work together to move your hand when you touch something hot?
Answer:
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain
Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.
Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.
Explanation:
Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.
When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.
For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.

Feeding problems may develop during the preschool years partially because of:_______
a. decreased appetite associated with decreased growth rate.
b. increased appetite associated with increased growth rate.
c. increased metabolic rate.
d. increased need for finger foods.
Answer:
The correct option is A.
decreased appetite associated with decreased growth rate
Explanation:
Feeding problems may develop in preschool age because of decreased appetite associated with decreased growth rate and this is because at the preschool age, there is no rapid growth, the growth rate is reduced which is as a result of decreased appetite for food. We all know that food supply the body with energy and necessary nutrients for growth. When there is decreased appetite enough food needed for growth will not be consumed , hence decrease growth rate.

What do you mean by adaptation?In biology, adaptation has three related meanings. It is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.
The ability of living organisms to adjust themselves to their surroundings is called adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.
Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.
