According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.
What is the kingdom protista?It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.
Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.
Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.

fill out the following about genetics:
Answer:
Define alleles:
Alleles are alternate forms of genes that are visible by mutations. They are found at a specific locus in a chromosome.
A. The genotypes of the parents: Ww and ww
B. The genotypic ratio of the offspring: 2:2
C. The phenotypic ratio of the offspring: 2:2
Explanation:
A white-fruited plant is crossed with a yellow-fruited plant. According to the instructions, the allele for white-fruited plants are dominant over the allele for yellow-fruited plants, this means that in order a plant to be white-fruited, they must either have the alleles Ww or WW. In this case, it is better to cross Ww, as all of the offsprings are yellow-fruited (ww).
Whenever we cross Ww and ww, we have a fifty percent chance of the offsprings either having the alleles "Ww" or "ww".
There are four smaller squares in a punnet square, and half of the smaller squares code for the alleles "Ww" and the other half code for the alleles "ww". This means that the genotypic ratio of the offspring would be 2:2, as 2 of the smaller squares code for "Ww", and the other 2 code for "ww".
Since "Ww" has a dominant allele, the phenotype for the organism with this genotype would be white-fruited, and for "ww", the phenotype for the organism would be yellow-fruited. This means that in this case, there would be a 50% chance for a white-fruited plant, and a 50% chance for a yellow-fruited plant. This is why the phenotypic ratio of the offspring would also be 2:2, as half of the smaller squares code for a plant with a white-fruited phenotype, and the other half of the smaller squares code for a plant with a yellow-fruited phenotype.
Which of the following precautions can help prevent mother-to-child HIV transm ensuring that an infected mother eats 10% more calories ensuring that an infected mother uses condoms starting an infected mother on antiretroviral treatment ensuring that an infected mother avoids antiretroviral treatment Question 3
A: Ensuring that an infected mother eats 10% more calories
B:Ensuring that an injected mother uses condoms
C:starting an infected mother on antiretroviral treatment
D:Ensuring that an infected mother avoids antiretroviral treatment
Answer:
C.
Explanation:
Antiretroviral treatment is the most effective way to prevent mother to child infections assuming she is already pregnant.
Wearing condoms only protects others
More calories only needs she's going to be feeding the baby more.
Avoidjng treatment only makes it worse thus making baby more susceptible to catching it.

What forms of hydrogen and oxygen are MOST
common on Earth?
A. Solid
B. Gas
C. Liquid
D. Plasma
Answer:
B
Explanation:
Hydrogen and Oxygen are the most abundant gases, being the first, and third most abundant.
Hope this helps, googIe only wanted to give me explanations on why Hydrogen is the most common element in the universe :/
The form of hydrogen and oxygen that are most common on Earth's surface is known as Gas. Thus, the correct option for this question is B.
What is the difference between hydrogen and oxygen?The difference between hydrogen and oxygen is that oxygen significantly contains eight electrons and eight protons while hydrogen contains only one electron and one proton. Oxygen is present in 21% of the earth's atmosphere, while hydrogen is present in 0.03% which is negligible.
According to the context of this question, oxygen is the first and most abundant gas in the earth's atmosphere and hydrogen is the third most abundant gas.
They are also present in the liquid and solid states but are in negligible amounts when treated with abnormal conditions like lower temperature and freezing.
Therefore, gaseous forms of hydrogen and oxygen are most common on Earth's surface. Thus, the correct option for this question is B.

An individual of genotype TtFFgg mates with an individual of genotype ttFfgg. About how many of their 100 offspring would you expect to be heterozygous for all three traits
Answer:
0
Explanation:
Heterozygous means that they have an allele for both traits and is in the form (Aa) meaning they have both the dominant and recessive trait.
We notice that the third trait, represented by 'g', is in the form gg for both individuals. Since they are both lowercase and the same allele, they are both hom0zygous for that trait, meaning there is no way the offspring can get a dominant trait to make their genotype Gg.

Which of the following farming approaches can grow food crops with less land use?
a. organic farming
b. vertical farming
c. industrial farming
d. biodynamic farming
Answer:
B. vertical farming
The farming approach that can grow food crops with less land use is option b, or "vertical farming," as it is an innovative farming approach that involves growing crops in vertically stacked layers.
What is vertical farming?Vertical farming is an innovative agricultural technique that involves growing crops in vertically stacked layers using artificial lighting and a soilless medium. The plants are grown in a controlled environment where all aspects of the growth process, such as temperature, humidity, and lighting, are carefully managed to optimize plant growth and yields, and vertical farming systems can be located in urban areas or other locations where land is limited or expensive. By growing crops vertically, the amount of land needed to produce a given amount of food is greatly reduced as compared to traditional farming methods that require large amounts of horizontal land.
Hence, the farming approach that can grow food crops with less land use is option b, vertical farming.
