"I can be single celled or multicelled. I can reproduce sexually or asexually. I can be heterotrophic or autotrophic. I am Eukaryotic. What am I?"
Answer:
The correct answer is a protist.
Explanation:
A eukaryotic organism, which cannot be categorized as an animal, plant, or fungus is known as protists. They are majorly unicellular, however, some of them are multicellular like algae. Some of the protists can attain energy for living by consuming other organisms, that is, they are heterotrophic. While some obtain energy from the surroundings via the process of photosynthesis, that is, they are also autotrophic.
The protists are mainly found in water, however, some of them also thrive in moist soil. These species can be seen anywhere on the Earth, where there is liquid, even within human beings. The reproduction is some of the protists takes place sexually, that is, with the help of gametes, while in some of the protists asexual reproduction also takes place, that is, by the process of binary fission.

The functions of the oral cavity include all of the following except Select one: A. mechanical processing of food. B. absorption of monosaccharides. C. digestion of carbohydrates. D. lubrication. E. sensory analysis of material before swallowing.
Answer:
C. Digestion of carbohydrates.
Explanation:
The function of the oral cavity that is not performed by the oral cavity is B) absorption of monosaccharides.
What is oral cavity?The oral cavity, also known as the mouth, plays a crucial role in the digestive process. Its main functions include mechanical processing of food by chewing and grinding, sensory analysis of material before swallowing through taste buds, and lubrication of food through the production of saliva.
The oral cavity also begins the process of digestion by breaking down carbohydrates with the help of enzymes in saliva. Additionally, the oral cavity serves as the entry point for air during breathing and speech. Proper oral health, including brushing, flossing, and regular dental check-ups, is important for maintaining overall health and wellness.

Which statement explains how a DNA mutation causes sickle-cell anemia? (point)
The DNA mutation increases the number of amino acids in hemoglobin, which causes a change in the shape of red blood cells.
The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.
The DNA mutation decreases the number of amino acids in hemoglobin, which causes a change in the shape of red blood cells.
O The DNA mutation prevents formation of hemoglobin, the absence of wirich causes a change in the shape of red blood cells.
Answer:
The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.
Explanation:
Sickle cell anemia is one of a group of disorders known as sickle cell disease. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body.
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.
Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin). In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky and misshapen.
The sickle cell mutation reflects a single change in the amino acid building blocks of the oxygen-transport protein, hemoglobin. This protein, which is the component that gives red cells their color, has two subunits. The alpha subunit is normal in people with sickle cell disease. The beta subunit has the amino acid valine at position 6 instead of the glutamic acid that is normally present. The alteration is the basis of all the problems that occur in people with sickle cell disease.
The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.
What is mutation?A mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA.
Moreover, a mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Therefore, when a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents.

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probability the offspring inherita
recessive short allele. (I point)
75%
25%
0%
50%
Answer:
The correct answer is - 25%.
Explanation:
A cross pollination between purebred tall pea plant and a heterozygous pea plant occurred as per the given condition. TT is the allele representation of the purebred plant and heterozygous plant is represented by Tt, so the gametes will be formed would be - T & T and T & t allele.
The Punnett square of this cross is attached with the answer,
So the probability of short allele would be:
= (2/8) *100 , (where 2 is the number of short allele in offspring where 8 is total number of alleles)
= (1/4) *100
= 25%

What is a biological approach to determining when a mother and her conceptus become separate individuals?
Answer:
Electroencephalography.
Explanation:
Electroencephalography is used to measure brain activity in terms of electrical activity. It is done by attaching electrodes on the scalp, or sometimes by placing electrodes directly in the brain. Using electroencephalography can help determine when the fetus starts having its own brain activities, which means that it is now a separate entity distinguishable from its mother. Using electroencephalography to see brain waves can give us a deeper insight into the age old complicated issue of when a mother and her conceptus become separate individuals.
