Which organelle controls what goes in and out of the cell? *
Mitochondria
Cell Membrane
The organelle that controls what goes in and out of the cell is the cell membrane, which is present in the second option. The cell membrane is the outer protective layer of the cell that does this function.
What is the role of the cell membrane?The cell membrane is the membrane that acts as the selective barrier for the cell, and through it, substances can enter and exit the cell. When energy is spent for the molecule to move, it is referred to as active transport; when it is not spent, it is referred to as passive transport.
Both eukaryotes and prokaryotes, as well as fungi, have different cell membrane compositions; some have more lipid content, some have less, some have cholesterol, and some don't. The lipids and proteins are arranged in such a way as to maintain cell homeostasis.
Hence, the organelle that controls what goes in and out of the cell is the cell membrane, which is present in the second option.

Question: How is wind speed and direction related to air temperature?
1. Think about it Imagine a pocket of air over the land ("land air"), and another pocket of air
over the ocean ("ocean air").
A Which air pocket would you expect to heat up more during the day?
Why?
B
Which air pocket would you expect to cool down more at night
Answer:
The wind moves from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses
Explanation:
Relationship between wind speed and direction to air temperature:
wind flows from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses.
A. The land air will heat up more during the day. This is because the land has a lower specific heat capacity than water, hence increases a lot more rapidly in temperature than the sea when the sun comes up.
B. The air packet over the land will cool down more rapidly at night due to the lower specific heat capacity of land when compared to the sea.
When resources are stable over a long period of time, a species' population can be expected to
O die out.
o increase.
O stay the same.
O decrease.
In an environment with stable availability of resources, the population can still grow because there are enough resources for this population to survive. Option B. The species' population can be expected to increase.
This question is related to growth models.
Logistic growthA growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
The population growth per capita rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Carrying capacityCarrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
• If the population size, N, is inferior to K (N<K), the population can still grow.
• When N approximates to K, the population´s growth speed decreases.
• When N=K, the population reaches equilibrium,
• When N is superior to K (N>K), the population must decrease in size because there are not enough resources to maintain that size.
So when the population size exceeds K, carrying capacity makes the population decrease in size.
But if there is a constant availability of resources, the population can still grow because there are enough resources for this population to survive. In this situation, N<K.
When resources are stable over a long period of time, a species' population can be expected to INCREASE. Option B.

One difference between gene mutation and chromosomal mutation that
Answer:
c. A chromosomal mutation can change the total number of chromosomes in the cell.
Explanation:
A gene mutation affects a single gene, and replication error is the main cause of gene mutation. A chromosomal mutation affects one part of chromosome or full chromosome. error in meiosis is the main cause of chromosomal mutation. Both mutations are responsible for a change in DNA. A chromosomal mutation leads to the change in total number of chromosomes in the cell.

Density is mass divided by volume (d = m ÷ v). Based on the graph, what happens to a fixed mass of water when it is cooled from 4°C to 0°C?
A.
volume increases and density decreases
B.
volume decreases and density increases
C.
volume increases and density increases
D.
volume decreases and density decreases
Answer:
The answer is A, Volume increases and density decreases
Explanation:
When water is cooled from 4°C to 0°C, the volume of water increases and density decreases. Thus, the correct option is A.
What is the Density of water?The density of water may be defined as the weight of the water per unit volume, which depends on the temperature of the water. The normal density of water is 997 kg/m³.
When the temperature of liquid goes down, the density of its gradually decreases, as a result of this, the volume considerably increases.
Therefore, the correct option for this question is A.

How does the lipid portion help maintain water concentration on each side of the bilateral?
Answer:
Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?
It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

What is the Precambrian time period?From roughly 4.6 billion years ago, when Earth first started to form, to the start of the Cambrian Period, 541 million years ago, is the Precambrian Period. It is the earliest era which is followed by the Cambrian period.
Large objects bombarded the Precambrian Earth, the crust was split into the first continents and ocean basins, crustal plates were mobilized, the atmosphere changed from reducing to oxidizing, and early life began and evolved. Climate and geologic events are responsible for the end of this period.
During this period, the amount of oxygen increased rapidly. Therefore, option C is correct.

A population of wolves migrate North in search of food. As the wolves travel they enter a region that has long, snowy Winters. This makes them better able to sneak up on prey.
A.) Give two reasons that the population is not a Hardy Weinberg equilibrium.
C.) How are the allele frequency change in the wolf population
Answer:
A, This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.
b,HW equilibrium means no selective pressures like the long, snowy winters selectively favoring the white coat phenotype over the other coat phenotypes. Selective pressures change the relative frequencies of the alleles in the gene pool. It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift.
