Which is a correct statement regarding the symmetry of the adult Porifera and the symmetry of the adult Cnidaria?
a. The Porifera are asymmetrical, while the Cnidaria are radially symmetrical.
b. The Cnidaria are asymmetrical, while the Porifera are radially symmetrical.
c. Both the Porifera and the Cnidaria are asymmetrical.
d. Both the Porifera and the Cnidaria are radially symmetrical.
Answer:
The correct answer is - a. The Porifera are asymmetrical, while the Cnidaria are radially symmetrical.
Explanation:
In biology, symmetry f the body is meant the presence of a pair of organs in an orderly manner that if divide the body each part is a mirror of the other. In the phylum Porifera have asymmetric body plane.
Some animals develop into adults with radial symmetry. Cnidaria adults have radial symmetry type of body plans that eans if they are cut from the middle they divide in the two equal organs into both sides.

Which group of organisms evolved first?
amphibians
fish
reptiles
mammals
Answer:
I'm pretty sure it's fish since they evolved into both reptiles and amphibians
Explanation:
The first creatures that evolved the first are fish. The first creatures they were evolved before amphibians,reptiles and mammals were fish.
What is the king organism of reptiles ?The king organism of reptiles category is crocodile.
Amphibians, reptiles, mammals and birds evolved after fish where the first amphibians that evolved from a lobe-finned fish ancestor about 365 million years ago. Fishes were the most earliest vertebrates to live on land but they had to return to water in order to reproduce.
The first vertebrates were therefore the fishes that had the different categories from chordates and vertebrates where few had the notochord and few had the vertebral columns.

How do craters on other solar system objects provide evidence about earth?
Answer:
The surfaces of asteroids and the rocky, ice covered moons of the outer gas planets are cratered as well. The craters left by impacting objects can reveal information about the age of a planet's surface and the nature and composition of the planet's surface at the time the crater was formed.

A scientist wants to increase the chance of pregnancy in mice. He gives the mice a hormone that causes them to produce more gametes. Which of the following statements justifies which process the cells went through after the hormone injections?
Answer:
C. Meiosis since it produces haploid cellsneeded for reproduction.
Meiosis since it produces haploid cells needed for reproduction justifies the process the cells went through after the hormone injections.
What is Meiosis?This is the type of cell division in which the parent cells produces four unique daughter cells and is involved in reproduction and gamete formation.
The hormone given to the mice to produce more gamete through the process of meiosis will produce haploid cells needed for reproduction.

What happens when the seafloor spreads?
When the head is tilted, what are the structures the signal passes through on its way to becoming a fully processed neural signal within the brain?
When the head is tilted, the fluid within the_____of the inner ear moves. The exact location of stimulated cells depends on the plane of movement-with each plane being represented by a different part of that structure. The movement of fluid stimulates______which transduce the signal into an electrical signal. This signal travels through the_____nerve to the____nucleus of the_____.
Answer:
The fluid within the semicircular ducts of the inner ear, that is, endolymph moves when the head is tilted. The precise position of the stimulated cells relies upon the plane of movement with each vertical or horizontal plane being signified by distinct parts of its composition. The hair cells that transduce the signal into an electrical signal get stimulated due to the movement of fluid. The conduction of this signal takes place via the auditory nerve to the cochlear nucleus of the brainstem.
Within the inner ear cochlea, the stimulation of the hair cells or stereocilia takes place by endolymph, it is a fluid present in semicircular ducts. After stimulation, the hair cells mediate electric signals to the brain via the auditory nerve, these are the nerve bundles that carry signals of sound. The initial central auditory composition found in the brainstem is the Cochlea nucleus.
Answer:
the fluid within the -semicircular canals- of the inner ear moves. the movement of the fluid stimulates the -hair cells- which transduce the signal into an electric signal. This signal travels through the -vestibulocochlear nerve- to the vestibular nucleus of the -medulla oblongata-.

Use the diagram below to help you to choose ALLL the CORRECT answers for the question: What are the differences between Meiosis i and Meiosis II?
(MULTIPLE CHOICE)
A In Metaphase I and Metaphase II the chromosomes line up differently because there are a different number of copies
B Telophase and cytokinesis do NOT happen in Meiosis II
C After Meiosis II the 4 daughter cells undergo cell specialization to become eggs or sperm, which does not happen after Meiosis I
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Answer:
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Explanation:
Meiosis is a type of cell division in which four daughter cells, which are genetically different from one another, are produced. The daughter cells have their chromosomal number reduced by half. Since, the meiotic process aims at producing haploid gametes, it occurs in a series of two-division steps viz: meiosis I and meiosis II.
Meiosis I involves the separation of homologous chromosomes into two daughter cells while the meiosis II involves separation of chromatids to make four daughter cells. One major difference between meiosis I and meiosis II is that in the PROPHASE of meiosis I, a unique process called CROSSING OVER occurs but does not occur in meiosis II (as seen in the attached image).
1. Imagine that the class had 25% of students with free earlobes and 75% with attached earlobes. What would this suggest about the frequency of the dominant (F) and recessive (f) alleles for these traits in the class population? Explain your reasoning.
Answer:
People with free earlobes carry one or two dominant alleles which means that the free earlobe is a dominant trait over attached earlobes that carries two recessive alleles. The recessive allele is represented by f and the dominant allele is represented by F.
It is given that in a class 25% of students in the class had free earlobes which means either 25% of total alleles are FF or Ff and the rest 75% have ff. It suggests that recessive alleles have more frequency than dominant alleles.

D
indoor air pollution.
Answer: global warming
Explanation:
Global warming is simply referred to as the long-term heating of the surface of the Earth and this is caused by human activities, and also the burning of primarily fossil fuel, which brings about the pumping of carbon dioxide, greenhouse gases and air pollutants into the atmosphere.
The weatherizing of buildings to reduce heat loss and save on fuel costs has led to an increase in global warming.
Enzymes are protein catalysts. What is the role of a catalyst?
Answer:
Enzymes are proteins functioning as catalysts that speed up reactions by lowering the activation energy. A simple and succinct definition of an enzyme is that it is a biological catalyst that accelerates a chemical reaction without altering its equilibrium.
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.
