How does the decrease in biodiversity impact an ecosystem?
Answer:
because the more alike species are The more they have to adapt to try and compete with one another So the more different a species is the less they have to compete
Answer:
the decrease in biodiversity may cause a significant reduction in the productivity of the ecosystem. The loss of biodiversity means genetic variations are lost and the overall genetic pool reduces.

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).

Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.

Which macromolecule is needed for lactic acid formation and alcohol fermentation to proceed with their processes?
IN YOUR OWN WORDS
DONT COPY FROM THE INTERNET
Answer:
sugar
Explanation:
sugar is the required macromolecule
In the lactic acid formation, pyruvate changes to the lactose which is the anaerobic form of respiration. Pyruvate changes to alcohol and carbon dioxide.
What is the main ingredient for lactic acid fermentation ?It is the sugar molecule that is needed for the lactic acid fermentation.
Both the types of the fermentation requires two primary components which are a sugar supply and bacterial culture where alcohol fermentation uses the forms of the yeast where the lactic acid fermentation usually depends on the lactic acid bacteria.
Lactic acid fermentation takes place in some of the strains of the bacteria and in the even skeletal muscle and even produces lactic acid . Alcoholic fermentation takes place in the yeast and just produces ethanol with carbon dioxide.
Lactic acid bacteria is a type of gram-+ve bacteria which use carbohydrates as only and main carbon source. Later on lactic acid bacteria is generally cocci or rods usually have the strong tolerance to low pH.

Biology homework please help
Answer:
muscles
ribs
lungs
bronchioles
alveoli
diffuses
leaves
exchange
Explanation:
Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.
Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter and brown mice survive better in the warmer months. If a group of these mice migrated to an area that didn't get snowy in the winter, what do you think would be the long term effect on the color of these mice? Explain why.
Answer:
The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.
Explanation:
As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.

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.
How do animal behaviors lead to successful reproduction and growth of their young?
Answer: Their actions help the young survive in the wild
Explanation: Examples of behaviors that affect the probability of animal reproduction could include nest building to protect young from cold, herding of animals to protect young from predators, and vocalization of animals and colorful plumage to attract mates for breeding.r
