Answers

Triticate is a crop species resulting from a plant breeder's cross between wheat (Triticum) and rye (Secale). It is produced by doubling chromosomes of the sterile hybrid that results when crossing wheat and rye. This doubling produces what is called a polyloid.

The function of the hepatic portal circulation is to ________.A. carry toxins to the venous system for disposal through the urinary tract
B. collect absorbed nutrients for metabolic processing or storage
C. distribute hormones
D. return glucose to the general circulation when blood sugar is low

Answers

The function of the hepatic portal circulation is to collect absorbed nutrients for metabolic processing or storage.

Final answer:

The hepatic portal circulation’s main function is to collect absorbed nutrients from digestion for metabolic processing or storage in the liver. It helps in controlling the quantity of available nutrients for the body's cells.

Explanation:

The function of the hepatic portal circulation is option B: to collect absorbed nutrients for metabolic processing or storage. The hepatic portal system is a critical part of the body's circulatory system. It carries blood from organs that digest food and drink, such as the stomach and intestines, to the liver. Here, the blood is processed to detoxify harmful substances, store nutrients, and send nutrients back into the bloodstream for the body to use. This process is key in maintaining stable levels of nutrients available to the body's cells.

An organism is multicellular, has chloroplasts, and is made up of eukaryotic cells. In which domain would a scientist place this organism?

Answers

The answer is Eukarya.

There are three domains in the tree of life: Archaea, Bacteria, and Eukarya. Archae and Bacteria are Prokaryotes, unicellular organisms without a nucleus and organelles. Eukarya mostly includes multicellular organisms with a nucleus and organelles.
The mentioned organism is multicellular made up of eukaryotic cells and has organelles (chloroplasts). According to the characteristics of three different domains, the organism could be placed only in the domain Eukarya.

Why do naturalists suggest that we plant more trees?

Answers

Naturalists would suggest that it is important to plant more trees so that we can avoid the effects that come alongside deforestation such as soil erosion and high levels of ozone. It is important not to underestimate the positive effect that trees have on the environment, in fact one tree can actually release enough oxygen to provide for two people over the course of their lifetime.

How do natural disasters contribute to genetic drift?

Answers

Final answer:

Natural disasters can lead to genetic drift by causing changes in population size and composition. They can result in the loss of genetic variation, founder effects, and bottleneck effects.

Explanation:

Natural disasters can contribute to genetic drift by causing significant changes in the population size and composition of a species. These events can lead to a random loss of genetic variation by causing the death of certain individuals or wiping out entire populations. For example, in a wildfire, individuals with certain genetic traits may be more vulnerable to the fire and are therefore less likely to survive and reproduce, leading to a decrease in the frequency of those traits in future generations.

In addition, natural disasters can also result in founder effects and bottleneck effects. A founder effect occurs when a small group of individuals become isolated from the larger population and establish a new population. The genetic diversity of this new population is greatly reduced compared to the original population, leading to genetic drift. Similarly, a bottleneck effect occurs when a large population undergoes a drastic reduction in size, reducing genetic diversity. Both of these effects can be caused by natural disasters, such as earthquakes or hurricanes.

Overall, natural disasters can have a significant impact on genetic drift by influencing the frequency and distribution of genetic traits within a population.
