Explanation:
Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. Vacuoles are somewhat larger than vesicles, and the membrane of a vacuole does not fuse with the membranes of other cellular components. Vesicles can fuse with other membranes within the cell system. Additionally, enzymes within plant vacuoles can break down macromolecules.

Lysosomes, Vesicles and vacuoles are membrane-bound sacs that provide storage and transport functions.
What is lysosomes?Lysosomes are defined as membrane-enclosed organelles containing a variety of enzymes capable of degrading all sorts of biological polymers, including proteins, nucleic acids, carbohydrates, and lipids.
It can also be defined as sphere-shaped vesicles or sacs containing hydrolytic enzymes capable of breaking down nearly all types of biomolecules.
Vacuoles are defined as a cell compartment that is devoid of cytoplasm, bordered with a membrane, and filled with fluid.
They are also defined as a membrane-bound organelle found in plant and fungal cells, as well as some protist, animal, and bacterial cells.
Vacuoles are slightly larger than vesicles, and their membranes do not merge with those of other cellular components.
Vesicles can join together with different membranes in the cell system. Enzymes found in plant vacuoles can also degrade macromolecules.
Thus, lysosomes, Vesicles and vacuoles are membrane-bound sacs that provide storage and transport functions.

why is it beneficial for female peacocks to choose to mate with a male peacock with a full colorful trains?
URGENT
Answer:
Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger at birth and better at surviving in the wild than offspring of birds with fewer eyespots.

how does the structural adaptation of seeds help them survive
Answer:
Explanation:
A seed is a plant embryo wrapped in a protective covering. A fruit is the ripened ovary of a plant which contains one or more seeds.
Most plants are rooted in place, which makes dispersing their fruits and seeds particularly important. Seeds that are spread far from the parent plant avoid competition with their relatives for resources and have the opportunity to colonize new areas. Both fruits and seeds have a variety of adaptations for different types of dispersal.
Examples of the some common types of dispersal follow.
Wind
<-- Left : These seeds are transported by air currents. Small fruit or seeds with fine fluff can be carried high up into the air. Herbaceous plants of open areas (like dandelions, cattails, and milkweeds) often have this adaptation. Their seeds float up over neighboring plants even if the parent is growing low to the ground.
Right -->: The fruit of maple trees are also adapted to catch the wind. Many trees (like ashes and sweetgums) have winged fruits or seeds which drop from the tree and are caught by the wind as they fall.
Water
<-- Left : Sea bean seeds are adapted for dispersal by ocean currents. Sea bean vines grow along rivers and coasts. When the pods ripen, they split open and the seeds drop into the water. The beans have a thick seed coat to keep the salt-water out, and have internal structures which make them buoyant enough to float. They can drift for hundreds of miles before washing up onto land.
Coconuts (which are single-seeded fruits) are also adapted for water dispersal. Like sea beans, they have a thick shell to prevent the salt-water from damaging the seed, and the buoyant hull keeps the nut floating.
Animals: internal transport
<-- Left : Brightly colored fruits advertise for dispersers. They are highly visible to birds, promising a nutritious (and often sugary) reward. The seeds are tough and usually undamaged when eaten. They are dispersed when the bird makes a rest stop.
Right -->: Immature seeds in unripe fruit would die if eaten. The green of young fruit hides them among leaves. Unripe fruit are sour or bitter to discourage animals that do find them. Green fruit cling tightly to the plant, making it hard for animals to remove them.
Animals: external transport
<-- Left: Cockle burrs are dry fruit adapted for animal dispersal. The hooked spines catch on the hair (or socks) of passing animals. Dispersal is complete when the animal picks off the offending burr, hopefully dropping it in a new location suitable for growth.
Right -->: Fruit of the unicorn plant have an unusual adaptation for transport. As grazing deer or antelope walk over them, the spines catch around the animals' feet. When the animal finally gets annoyed and shakes the fruit off, dispersal is complete.
Which of the following is a true statement about lipids in cell members
A. Hydrophobic lipids heads are attracted to water
B. Hydrophobic lipid fatty acid tails turn turn away(repel)from water
C. A bilayer forms when lipid heads turn toward water inside and outside the cell
D. All are correct
Answer:
it is option B this is correct
Hydrophobic lipid fatty acid tails turn away that is they repel from water as lipids are fat insoluble which are present in cell membrane. Thus, the correct option is B.
What are the lipids in cell membrane?Lipid molecules are hydrophobic in nature. There are three major classes of membrane lipid molecules including phospholipids, cholesterol, and glycolipids. The lipid composition of the inner and the outer monolayers are different from each other, this reflect different functions of the two faces of the cell membrane.
The most important lipid component of the plasma membrane is Fatty acid. An fatty acid is a monocarboxylic acid with a long generally 14 to 24 carbons long chain, it is unbranched, hydrophobic tail which may be either saturated or unsaturated with zero to six cis, non-conjugated double bonds in the compound. The hydrophobic lipid fatty acid tails turn away or repel from water.
Therefore, the correct option is B.

What is the overall purpose of meiosis?
Choose 1 answer:
А
To repair damaged body cells
B
To create gametes
To produce a zygote
D
To grow new somatic cells
Answer:
D
Explanation:
The purpose of meiosis is to produce gametes, somatic cells or sex cells. So The answer would be D
To grow new somatic cells is the overall purpose of meiosis.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
The purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells. In the figures below, pink represents a genetic contribution from mom and blue represents a genetic contribution from dad.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Which of the following normally leads to the production of functional messenger RNA in eukaryotic cells?
Answer: The removal of portions of RNA known as intervening sequences (introns)
Explanation:
The removal of portions of RNA is known as intervening sequences (introns).
What is the process of splicing?In order to enable the translation of mRNA into a protein, RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.
Intron sequences are cut out and exon sequences are joined during the splicing process.
As RNA matures, introns are cut out via RNA splicing, which means that they are not expressed in the resulting messenger RNA (mRNA) product.
In contrast, exons continue to be chemically bound to one another to produce mature mRNA. Exons are expressed sequences, whereas introns can be thought of as intervening sequences.
Therefore, the removal of portions of RNA is known as intervening sequences (introns).
