Why do you think it would be important to know that both sides of the heart receive blood at the same time? Giving Brainliest
Explanation:
The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body. If your body didn't do it simultaneously, then blood would overflow your lungs.

Q.2. Describe the different phases of meiotic prophase – I. Mention the chromosomal events during each stage.
Prophase-I occurs over a long duration and involves several complicated changes in meiotic cell division. It is important because genetic recombineiion and variation in sexually reproducing organism occurs due to the events of this phase.
EXPLANATION:❈ Leptotene —
➥ The chromatin network opens out and threads become clear.
➥ The chromosomes are thin, slender and long.
➥ Chromosome number is diploid.
❈ Zygotene —
➥ Corresponding chromosomes become intimately associated.
➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.
➥ The chromosomes become shorter and thicker.
❈ Pachytene or Pachynema —
➥ The synaptic chromosomes become very intimately associated.
➥ The pair of chromosomes becomes short and thick.
➥ Crossing over occurs at this stage. Chiasmata are clearly seen.
❈ Diplotene —
➥ Homologous chromosomes start separating from one another.
➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.
➥ Chromosomes start separating out but the separation is not complete.
➥ Nuclear membrane and nucleolus start disappearing.
❈ Diakinesis —
➥ The bivalents condense further and get randomly distributed.
➥ The separation of paired chromosomes is almost complete.
➥ Terminalisation of chiasmata is almost complete.
➥ Nuclear membrane and nucleolus disappear.
What type of energy transformation takes place during cellular respiration?
Answer: The energy transformation that takes place during cellular respiration is the conversion of glucose (chemical energy) to another form of compound with high energy bonds (adenosine triphosphate) that can be readily used by the body. All energy on Earth comes from the sun.
Explanation:
An allele arises in a population that helps individuals digest cellulose. While the allele starts in only one organism, it increases in allele frequency because it allows organisms that carry it to reproduce more. What is this an example of
ANSWER: A NATURAL SELECTION.
EXPLANATION:
When allele has direct effects on the organism and the environment, it is termed natural selection. It either affects an organism positively by causing more DNA reproduction, leading to the increase in allele’s frequency, or negatively by decreasing it .
However, this shouldn't be mistakened for genetic drift, where allele increase or decrease is established in the random organisms that survived.
What type of reproduction involves forming offspring from two
parents?
a Asexual
b Sexual
C Mitosis
int?
d Replication
Answer:
Sexual
Explanation:
Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Hope it helps
Answer: Sexual, I believe.
Explanation:
If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

Ok, do we live in or on earth?
Answer:

Which two viral characteristics provide evidence to support the
argument that viruses are more similar to living components than to
nonliving components of an ecosystem?
Living Characteristics of Viruses Nonliving Characteristics of Viruses They reproduce at a fantastic rate but only in living host cells. They can mutate. They are acellular that is they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.

The state of Illinois has a law that requires 25% of electricity in the state 2 be produced by renewable energy sources by the year 2025. This law is an example of
a. Green pricing
b. A renewable portfolio
c. An Energy Star promotional program
Answer:
b. A renewable portfolio
Explanation:
A renewable portfolio refers to the policies that are designed to increase the use of renewable energy sources for electricity generation. These renewable energy sources such as water, wind and solar radiation etc are used for the generation of electricity and also to reduce pollution in the environment. These renewable energy sources are present unlimited or in huge amount in our environment so its usage is beneficial for both humans and environment.
A sexually mature seahorse can produce thousands of offspring. What is the BEST reason overproduction of offspring by marine organisms is considered to be a reproductive advantage?
It increases competition.
It decreases competition.
It contributes to the organism’s biological success.
It causes stress on the environment which will apply stress to the creature to adapt.
Answer: D
Explanation:
There are large number of predators present in marine environment. Overproduction of offspring contributes the biological success of the organism.
What is overproduction?Overproduction is referred to the production of large number of species which can be physically supported by ecosystem.
Overproduction support survival of the fittest, by improving the genetic line.
Since the predators are more so, only that organism will survive who can adapt according to the that. This can contributes in organism's biological success.
Thus, the correct answer is C.

how genes control many of the characteristics of the organisms? answer asap pls
Answer:
To summarize, two things determine the traits an organism has: its genotype and the dominance or recessiveness of the alleles it has. Some traits, like flower color in peas, are controlled by a single gene, but ultimately many if not most traits in an organism are controlled by more than one gene
