Answer:

Predator foraging traits include;

Prey vulnerability traits include;

But whether or not predators engage with prey, or prey respond to predators in the first place, depends fundamentally on their relative body sizes (or predator gape and prey body shape). Pursuing prey that are too large or cumbersome can be harmful or energetically costly to predators, and pursuing prey that are too small may not be worth the energetic return.

As these populations continue to reproduce over time, the actions of natural selection can also change the species to make them better predators, or more defensive prey. Either way, this adaptation changes the entire predator prey dynamic. If one species cannot then adapt an appropriate defense, they may go extinct.

Answer:

Option A. Sodium is needed to generate an action potential.

Explanation:

Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.

These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.

When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.

Proteins are the macro-molecule whose smallest unit is amino acid. Genes contains some information necessary for protein formation.

Amino acids are the organic compounds that is mixture of one amino and one carboxylate group.

There are 20 sets of amino acids that are used as building blocks of protein.

The sequence of the amino acid causes the protein to fold into a shape which is biologically active. Genes encode the amino acid sequence of protein.

Thus, the correct option is A.

Answer:ur answer is protozoa

Explanation:

In cladistics or phylogenetics, an outgroup is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of organisms under study, and is distinct from sociological outgroups.

The out group in this cladogram is protozoa that is distantly related to the other organism s in the given cladogram.

The out group is a creature that is only distantly connected to the other creatures on the cladogram. The out group, which is commonly assumed to represent the ancestral situation from which the organisms in the cladogram later evolved, contributes to the tree's roots.

The organisms in the in-group are connected to one another. The cladogram is founded on the introduction of a distantly related creature known as the out group. The out group is frequently represented by a single branch on the cladogram.

Out group is an evolutionary phrase that refers to a taxon or lineage that is not part of the taxon group being examined.

Thus, the out group in this cladogram is protozoa.

Answer:

c.) deforestation

Explanation:

"Lack of shade" means that the ponds no longer have enough coverage over them such that the sun shines strong above the river causing it to dry up. Trees are mostly huge tall and are very likely to provide shade for the river originally, and since deforestation means the mass cutting down of trees, the answer is c.

carbon monoxide

Explanation:

sulfuric acid is litterally acid

sodium hydroxide..... common now

Carbon monoxide (c.) is the gas that makes up the majority of air pollutants.

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced by the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, coal, and wood. It is a highly toxic gas and can be harmful to both humans and animals.

When inhaled, carbon monoxide enters the bloodstream and binds to hemoglobin, the molecule responsible for carrying oxygen to body tissues. This binding affinity is much stronger than that of oxygen, resulting in reduced oxygen delivery to organs and tissues. As a result, exposure to high levels of carbon monoxide can lead to symptoms such as headache, dizziness, nausea, confusion, and in severe cases, loss of consciousness and death.

Carbon monoxide is a significant air pollutant, often found in areas with heavy traffic, industrial emissions, and improper ventilation. It is important to have proper ventilation systems and to use carbon monoxide detectors to minimize the risk of exposure to this dangerous gas.

Answer:

1. Latitude. Kuala Lumpur is located in the equatorial zone, near the equator, so it receives a lot of sun for the  entire year, and this explains its warm climate.

2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.

3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.

4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.

Coral reef damage negatively affects the land primarily by causing a loss of cures. Hence the correct option is B.

1. Loss of cures: Coral reefs are incredibly diverse ecosystems that provide numerous ecological and economic benefits. One significant impact of coral reef damage is the loss of potential cures and medicinal resources. Many marine organisms, including those found in coral reefs, contain bioactive compounds that have the potential for developing new medicines, treatments, and therapies. By damaging coral reefs, we risk losing these valuable resources and potential cures for various diseases.

2. Biodiversity decline: While option A, "There is more biodiversity," is incorrect in this case, it is important to note that coral reefs are known as the "rainforests of the sea" due to their high biodiversity. Coral reefs support a wide range of marine species, providing habitats, shelter, and food sources. When coral reefs are damaged, either through human activities like pollution, overfishing, or climate change-related factors like coral bleaching, the biodiversity of the reef ecosystem decreases.

3. Land erosion: Option C, "There is more land erosion," is not typically a direct consequence of coral reef damage. However, healthy coral reefs do play a role in protecting the coastline from erosion. Coral reefs act as natural barriers that help dissipate the energy of waves, reducing wave-induced erosion and protecting nearby coastlines from storms and wave action. When coral reefs are damaged or destroyed, the protective function of the reef is lost, potentially leading to increased erosion of the nearby land.

Hence the correct option is B

Let +W+ = wages/wk earned

Let +h+ = hours/wk worked

The equation is:
