Answer:
when small molecules pass through the lipid bilayer of a cell membrane simple passive diffusion occurs
Explanation:
Diffusion is one form of passive transport that doesn't require the expenditure of cellular energy. A molecule can diffuse passively through the cell membrane if it's lipid-soluble, uncharged, and very small, or if a carrier molecule can assist it. ... The assisted process is known as facilitated diffusion.

What is the function of the sporangium?
Answer:
A sprongium is a structure in certain plants and other organisims that is charged with making and storing spores.
Explanation:
"A sporangium (plural: sporangia) is the capsule structure belonging to many plants and fungi, in which the reproductive spores are produced and stored. All land plants undergo an alteration of generations to reproduce; the sporangium is borne upon the sporophyte, which is the asexual second generation structure."

Gregor is planting pea plants in his backyard. Some of the plants are tall and the rest are short. Some of the plants are yellow and the rest are green. The numbers of different plant types are in the ratio[{Tall green}:{Tall yellow}:{Short green}:{Short yellow} = 8:5:2:1. If there are 1080 green plants, then how many total plants are in Gregor's yard?
Answer: 1732
Explanation:
infer short, yellow are recessive
8TG, 5Tg, 2tG, 1tg
proportion of green plants = 10/16
so total plants = 1080*16/10 = 1732

(T/F) Most cells reach a certain size, stop growing, and then divide.
Answer:
True
Explanation:
Most of the cells in the body of an organism reach a certain size, stop growing after a certain size, and then undergo division. Cells maintain the cell number in body through continuous division. Thus, the given statement is true.
What are Cells?Cells are the basic unit of life. Cells are the building blocks of living organisms. The human body is composed of cells. These cells provide the structure for the body, take in nutrients from food, convert the nutrients into usable form of energy, and carry out specialized functions such as digestion, respiration, excretion, and circulation, etc.
Specialized cells in the body of an organism have a certain size and shape and these undergo growth and division. Cells undergo cell cycle which consists of different phases such as interphase and M-phase where the cell grows in size and shape and divides to form more cells and thus maintain their number.

Which event in meiosis increases genetic variation within a population?
A. DNA condenses to form chromosomes.
B. Segments of chromosomes cross over.
C. Chromosomes duplicate themselves.
D. Chromosomes form pairs.
Answer:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occur during prophase 1
1. Which image represents the flow of a longshore current in relation to a sandy beach?
Answer: Option C
Explanation:
When waves of water approach the beach, they do so as an angle because they have been slowed down by the first parts of the beach that they have encountered.
When they hit the beach at an angle, they come back to the water and keep doing so like the movement shown in option D. This constant motion moves the sand and other particles on the beach progressively and the current that does so is the Longshore current which moves parallel to the coastline.

Which physical property is most helpful for separating a mixture of sand and
gravel?
A. Particle density
B. Boiling point
C. Particle size
D. Magnetic attraction
Various methods can be employed in the separation of heterogeneous mixtures from a solution comprising the solute and the solvent.
The correct answer is:
Option C. Particle Size.
This can be explained as:
Sand and gravel have two different sizes and can be separated on the basis of particle sizes.Sieving is a method that can be employed to separate gravel from sand.Sand particles being small will pass through the sieve while gravel being big in size will remain on the top of the sieve.Therefore, particle size will be the parameter by which sand and gravel can be separated.

Mitosis produces which cell type?
haploid
diploid
chromosome
gamete
Answer:
b, diploid.
Explanation:
Mitosis produces two diploid somatic cells, genetically identical to each other and the parent cell.
Mitosis produces diploid cells (option B)
What is Mitosis?Mitosis is a process of cell division observed in cells. Its primary purpose is to ensure that the genetic information, in the parent cell is equally distributed among the resulting daughter cells.
During mitosis the process generates cells that are diploid, meaning that the number of chromosomes in the parent cell is the same as the number in the resulting daughter cells.
In contrast haploid cells have half the number of chromosomes found in cells. Examples of haploid cells include sperm and eggs which are known as gametes.
Notably, we can conclude that mitosis produces diploid cells (option B)

What type of variation is nessary for natural selection to occur
Answer:
Genetic variation
Explanation:
Genetic variability (diversity) stems from two basic processes: mutation and recombination.
If there were no mutations, all genes would exist in only one form, they would not have alternative forms.
Since phenotypic variability also depends on genetic variability, it is clear that the processes of mutation and recombination contribute to the creation of a large number of different phenotypes.
someone may ask you to distill a complicated idea into a brief summary that gets right to the point. how does this relate to distillation in chemistry
Answer:To separate two or more liquids by distillation, you first heat them in a flask. The more volatile liquid (the liquid with the lower boiling point) will typically evaporate first and the vapor will pass into a ... the refluxing liquid can condense, re-evaporate, and condense again, essentially distilling the ...
Explanation:
Distilling a complicated idea into brief summary that gets right to the point relates with distillation in chemistry in that both requires breaking a complex idea/substance into smaller component pieces.
In chemistry, distillation is a technique used for separating a liquid mixture into its components by allowing each component to boil, evaporate off the mixture, and then allowed to condense.
Because the each component of a mixture has different boiling point, this attribute is applied in distillation. The mixture is placed in a distiller and heated. At their respective boiling temperature, each component evaporates off the mixture and condenses at a collection point by a cooling water.
This is what it means when a complicated idea is being asked to be distilled. Such idea is to be broken down into smaller, concise ideas that can easily be executed as part of the whole idea.
