Answer:
C. Eukarya
Explanation:
When a plant or animal is no longer found anywhere on Earth, it is described as
being
locally extinct
geographically extinct
biologically threatened
biologically extinct
Answer:
B. Geographically extinct
Explanation:
Lets take a moment to look at the words provided. Geographical means physical features of an area, or relating to geography. It can also relate to when we are talking about information on the Earth's surface. Extinct means that the organism is no longer alive, and that there are none left of its species. So, putting the two words together, geographically extinct means that the organism is no longer found on Earth.

find out what do the terms algal bloom and red tides signify
Answer:
Find out what do the terms 'algal bloom' and 'red-tides' signify. Algal bloom refers to an increase in the population of algae or blue-green algae in water due to an enrichment of nutrients, resulting in discoloration of the water body. ... Red tides are caused by red dinoflagellates (Gonyaulax) that multiply rapidly.
I hope it's helpful!
Answer:
Algal bloom refers to vigorous growth of algae or blue-green algae in water, due to enrichment of water body with minerals nutrients coming from fields, resulting in discoloration of the water body. This causes an increase in the biological oxygen demand (BOD), resulting in the death of fishes and other aquatic animals, due to suffocation.
Explanation:
Suppose the phloem of a seed plant is damaged and does not function properly.
How will this most directly affect the plant?
Answer:
Food will not be carried away from the leaves
Explanation:
Suppose that the same island experiences environmental
conditions that prevent the growth of large seeds. What do you think would happen to
the average size of finch beaks? Explain your reasoning.
Answer:
The size of finch's beak depends on the size of seeds.
Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.

If a gene has two alleles, there are two possible genotypes.
a. True
b. False
Answer:
b. False
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.
The three (3) possible genotypes are;
I. A combination of alleles such as AA.
II. A dominant combination (phenotype) such as Aa.
III. A recessive combination such as aa.
Where;
A represents the dominant allelea represents the recessive allele.Also, a single version of a gene expressed by a living organism is referred to as an allele.
Mitosis vs Meiosis, someone help me with this, ill give brainiest.
Mitosis gives two nuclei, and hence two cells while meiosis gives four.
2. CellsMitosis gives identical cells to each other and to the mother cell while meiosis leads to genetic variation due to crossing over and independent assortment.
3.DivisionMitosis includes one division while meiosis includes two.
4. Crossing overIt takes place in Meiosis while absence in Mitosis.
5. ChromosomesMitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes)

Examining different cells such as the plants, animal, and fungus cells. Identify the different organelles found in different cells and list the organelles and structures the characterize each of them.
Answer: Organelle is a sub-unit of cell and it is involved in performing specialized function within the cell. The type of organelles vary from organisms to organisms.
Explanation:
1. Centrioles are the cell organelles in which the spindle fibers are organized to which the chromosomes attach and mitotic division takes place. These are present only in animals and they are absent in plant and fungal cells.
2. Vacuoles are the storage organelles which store excess water, waste metabolites, sugars and other components in them. In plant cells they are of larger size whereas the vacuoles are small in size in case of the animal and fungal cells.
3. The plants cells and fungal cells have cell wall made up of cellulose (plants) and chitin (fungus) respectively. The cell wall is absent in animal cells.
4. The plant cells and fungal cells do not possess cilia and flagella for locomotion whereas animal cells have cilia and flagella.

During the process of photosynthesis, green plants produce...
(1) sunlight
(3) nitrogen
(2) methane
(4) sugar
Answer:

Explanation:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel
Why can mRNA leave the nucleus, but
DNA cannot leave the nucleus?
A. DNA is single stranded and is too long to leave the
nucleus.
B. RNA is singled stranded, DNA is double stranded, so
RNA is smaller than DNA.
C. DNA can leave the nucleus through special openings in
the nuclear membrane.
D. DNA and RNA can both leave the nucleus.
Answer:
B
Explanation:
Your DNA is stored in a double helix formation. Which means it has two long strands and would be too long to leave the nucleus. C and A are incorrect. DNA is double stranded, so we can eliminate A. There are NO special openings in the nucleus. Only the cell membrane. C is eliminated.
Option D is incorrect because DNA is transcribed into the cell membrane, there is no way for it to leave. RNA is a single strand.
mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.
What is DNA?DNA stands for Deoxyribonucleic acid. It may be characterized as a type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. These molecules allow this information to be passed from one generation to the next.
DNA is not a single-stranded structure. While RNA is present in a single stranded form in the cell. Due to this, the double-stranded structure of DNA seems longer than that of RNA to cross the nuclear membrane in the cell. As a result of this, RNA can easily leave the nucleus but DNA couldn't.
Therefore, mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.

What characteristic do sea stars and brittle stars have in common?
Both have flexible joints.
Both have teeth-like feeding structures.
Both use tube feet to catch prey.
Both have tentacles.
Answer:
They typically have a tough, spiny surface, which inspired their name (in Greek, echinos means “spiny” and derma means “skin”). They also have the unusual ability to regrow lost body parts, and sea stars and brittle stars can regrow arms if broken off or eaten
Explanation:
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.
What are sea stars and brittle stars?Echinoderms with a star form that belongs to the class Asteroidea are known as starfish or sea stars. These terms are frequently used incorrectly to refer to ophiuroids, which are properly called brittle stars or basket stars in common usage. Due to their membership in the class Asteroidea, starfish are also referred to as asteroids.
The benthic (bottom-feeding) fauna of the maritime environment includes brittle stars. They belong to the Phylum Echinodermata, which includes marine organisms with radial symmetry, five components, and frequent spines. They are commonly referred to as echinoderms.
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.
