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.

What are ethical concerns in using animals for research?
Select all that apply.
Animals cannot consent to being used in experiments.
Animals are ideal biological models for experiments
Many animals can be studied at one time.
Some animals may have adverse reactions.
Answer: Animals cannot consent to being used in experiments.
Explanation:
Animals are not suitable options for the biological research as they are getting extinct and their population size is getting decreased. Option A is correct.
What are extinct species ?These are the species that are getting diminished from planet because of certain factors such as loss of habitat and many other crucial factors that affecting their growth.
Animals can not be used in the biological research as they are not able to speak the language which is understood by humans and ideally it is not right to do dissection over living beings.
Animals earlier were definitely considered for the experiment but the awareness of ethics and sensitivity of the issues is bringing down the ban on the animal crimes along with the lab research.
Ethical concerns are as well that without God's permission it is not right to harm the living beings.
Therefore, option B is correct.

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.

Which of the following answers is NOT correct with regard to convection currents?
A. Convection currents in magma drive plate tectonics.
B.Convection currents in magma are a result of density differences.
C. Convection currents play a role in the movement of Earth’s inner core.
D. Convection currents in magma are caused by temperature differences.
Answer: C....Convection currents play a role in the movement of Earth’s inner core
The statement which is not correct with regard to convection currents is as follows:
Convection currents play a role in the movement of Earth’s inner core.Thus, the correct option for this question is C.
What is Convection current?Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.
The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.
Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.
Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.
Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.
Therefore, the correct option for this question is C.

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.

The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced round seeds. However, in the fifth generation, the plant produced to two plants with wrinkled seeds. Can that be possible? Explain your answer using your pedigree chart.
Answer:
Explanation:
This happened because two fully recessive plants where introduced into the lineage. these plants where paired with the dominate verison. this would make all of the offspring have the two traits. this being said it would make it possible for the offspring to be Wrinkled Seeds.
When two heter0zyg0us individuals are crossed -simple d0minant inheritance-, or a heter0zyg0us individual is crossed with a h0m0zyg0us recessive one, they can produce h0m0zyg0us recessive subjects among the progeny. Heter0zyg0us individuals among the fourth generation got crossed with another plant (h0m0zyg0us recessive or heter0zyg0us) and produced two h0m0zyg0us recessive plants expressing wrinkle seeds.
---------------------------
The first step is to understand the given information. So,
The first four generations produced round seedsPlants that fertilized these plants also produced round seeds (see generation II) Among the fifth generation there are two plants with wrinkled seedsLet us assume that a diallelic gene determines the shape of seeds.
D0minant allele R codes for round seedsRecessive allele r codes for wrinkle seedsNow, let us analyze the pedigree. According to the information provided here, we can tell that
black figures represent h0m0zyg0us d0minant individuals, grey figures represent heter0zyg0us individualsempty figures represent h0m0zyg0us recessive individualsRemember that Generations are represented with roman numbers.
We will name the plants with numbers from 1 to 26.
According to the information in the statement and the information in the pedigree, we can say that grey individuals from the fourth generation are heter0zyg0us expressing round seeds. They can produce wrinkle seeds, if they are fertilized by another heter0zyg0us plant or a h0m0zygous recessive one.
Option 1:
Two heter0zyg0us plants are crossed, and their offspring have wrinkled seeds.
Option 2:
One heter0zyg0us plant is crossed with a h0m0zyg0us recessive one, and their offspring have wrinkled seeds. Let us see the cross
