Which term is not the name of a classification level?a. allele
b. kingdom
c. order
d. phylum

Answers

Answer 1

Answer:

Allele is not the name of a classification level because its not a part of taxonomical hierarchy. Therefore, option (A) is correct.

What is Taxonomic Hierarchy?

Taxonomic rank is the relative level of a group of organisms, known as a taxon, within an ancestral or hereditary hierarchy. This term is used in the field of biological categorization.

The Linnean system is the foundation for the modern method of classification, which consists of eight different levels of taxa. These levels, which are listed from most general to most specific, are as follows: domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.

What enables Dna to have so many variations with only 4 chemicals?

Answers

Answer:

Different combinations between these four set of chemicals

Explanation:

There can be billions of combinations between the four chemicals of DNA. The four set of chemicals i.e nucleotide (generally referred to as bases) namely -

A- Adenine

T- Thymine

C - Cytosine

G - Guanine

These nucleotide form codon i.e set of three nucleotide and form chain structure which can be long up to any extent.

Codon example - ATC TGA

Thus, variation in combination of four nucleotide and ability to form long chain of codon allows DNA to have several forms and variations

Even though DNA only has 4 nitrogenous bases there can be variety of combinations for DNA. One difference in combination would mean a different DNA strand.

Match the sedimentary rock with its metamorphic equivalent. 1. slate A; sandstone B;shale C;limestone D;coal 2. graphite A; sandstone B;shale C;limestone D;coal

Answers

I've matched it like this, check it out:
slate - shale
sandstone - quartzite
coal - graphite
limestone - marble
I hope it helps.

Answer;

Shale - slate
Sandstone - Quartzite
Coal - graphite
Limestone - marble

Explanation;

Metamorphic rocks are those rocks that may have originally been sedimentary, igneous, or other metamorphic rocks, which were then subjected to different conditions such as new temperatures and pressures, that made them to recrystallize and form completely new forms of rocks.
For examples, when limestone is subjected to heat and pressure it turns to marble. Shale when subjected to pressure it becomes slate which is a harder rock. Sandstone becomes Quartzite under pressure.

The _____ theory proposes that the moon was a passing asteroid pulled into orbit by Earth's gravity

Answers

It is the theory of capture, which proposes that the moon was an asteroid, this theory was in 1980 and was based on the capture of the moon by the land that was released and was trapped in the gravity of the earth. This happened also on other planets, but it was the study of the moon in which he had more emphasis.

Which of the following describes how polluted water sources would most likely affect one’s personal health?Answer
Bacteria would enter the body and inhibit a specific immune response.
Microorganisms would release histamine, causing inflammation and swelling.
Infectious agents would prevent the immune system from producing lymphocytes.
Pathogens would invade the body and cause disease, such as giardia.

Answers

I think the correct answer from the choices listed above is the last option. Polluted water sources would most likely affect one’s personal health since pathogens would invade the body and cause disease, such as giardia. Pathogens would go with the water we take in our body and would disturb the processes inside causing illnesses.

Answer: Pathogens would invade the body and cause disease, such as giardia.

Explanation:

The water body get polluted by the disposal of biological and non-biological wastes liberated by the human society so as to get rid of those wastes. The biological wastes includes the slurry of sewage which mainly includes the human and animal fecal matter which includes the pathogens which colonize and deteriorates the quality of water.

If the water from such water body if taken for the purpose of drinking, cooking and other crucial activities will likely to introduce the pathogens into the human body which invade the human immune system and can cause deadly diseases such as giardia.

Fertilization of the human egg cell usually occurs in thea. uterus.
b. vagina.
c. fallopian tube.
d. ovary.

Answers

The uterus- the ovaries are where the eggs are formed and are transported to the uterus by the fallopian tubes.

Final answer:

Fertilization in humans, which is the union of an egg and a sperm, mostly occurs in the fallopian tube. The egg, after being released from the ovary during ovulation, travels down the fallopian tube where fertilization by a sperm can occur.

Explanation:

The fertilization of the human egg typically occurs in the fallopian tube, which is option c. This process is part of the reproductive cycle where the egg, released from the ovary during ovulation, travels down the fallopian tube. At the same time, sperm, after ejaculation, travels from the vagina through the uterus to meet the egg in the fallopian tube. If a sperm successfully penetrates the egg, fertilization occurs, resulting in a zygote which will eventually travel to the uterus for implantation. Hence, the fertilization site is typically the fallopian tube, not the uterus, vagina, or ovary.
