Answer:

D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species

Explanation:

During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.

<h2>Elk forested Area Avoid Riverbanks</h2>

Explanation:

  • Predators clearly can impact the size of prey species populaces through direct mortality, which, can impact all out scavenging pressure on explicit plant species or whole plant networks  
  • Predation hazard can likewise have populace ramifications for prey by expanding mortality, as indicated by the "predation delicate nourishment" theory  
  • The Gros Ventre River, which depletes around 600 square miles of eastern Jackson Hole and the mountains more remote east is the biggest waterway on the asylum. The generally wide stream diverts are vigorously meshed in territories where geologic materials are of low erosional opposition, just like the case on the shelter. The various rock bars in the river channel have next to zero vegetative spread, thus, of yearly flooding and disintegration
  • Hence, the right answer is "Elk tend to avoid riparian areas and wooded riverbanks"

How are vascular and non-vascular plants different, and how do each of them work through osmosis?
Lilit [14]

Answer:

Explanation:

Vascular plants have tubelike structures that carry water, nutrients, and other substances throughout the plant. Nonvascular plants do not have these tubelike structures and use other ways to move water and substances.

Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues. Non-vascular plants do not have true roots, stems, or leaves and the tissues present are the least specialized forms of tissue. Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses. Some examples of non-vascular plants include moss, algae, liverwort, and hornwort.

How vascular plants work through osmosis

The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots to the rest of the plant. Through the xylem vessels, water enters and leaves cells through osmosis.

How non vascular plants work through osmosis

Because non vascular plants do not have the xylem and phloem ystem, they absorb water right into their cells through their leaves when it rains or when dew falls. Internal cells get their water by passive osmosis. While, they use rhizoids to transport nutrients and minerals.

The rate and direction of reactions are greatly influenced by
zlopas [31]

Answer:

reactions

Explanation:

Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.

The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle
vagabundo [1.1K]

Answer:

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Explanation:

Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)
