what role does the diaphragm play in breathing ?
Answer:
When the lungs inhale, the diaphragmcontracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside.the diaphragm plays an important role in breathing, it helps you inhale and exhale air

we can say that (F) is the dominant healthy gene and (f)is the recessive anemia gene
Falconi anemia is a recessive autosomal disease, therefore it will affect men and women equally
1)Arlene's genotype is (ff)
2)Ann's genotype is (Ff)(she's a carrier). Michael's genotype is (Ff)(also a carrier)
3)George's genotype is (Ff)
4)Sandra's genotype is, most likely (FF)
5)Sam, Ann and Michael are most likely carriers.
A veterinarian conducts a study of meiosis in dogs. She observes that during anaphase I, there are 39 pairs of chromosomes being pulled toward opposite ends of the cell. Which of the following statements is false? A. Crossing over has already taken place. B. The diploid number for dogs is 78. C. There will be 39 chromosomes in each dog gamete. D. Each gamete will have two alleles for each gene.
Answer:
D. Each gamete will have two alleles for each gene.
Explanation:
Gametes are haploid (n) reproductive cells. In animals, female gametes are known as egg cells, while male gametes are sperm cells. Each gamete (either female gamete or male gamete) contains a complete set of chromosomes which in turn have a complete set of gene variants (i.e., alleles). In consequence, for each gene, the dog's progeny will inherit one allele from the father and one complementary allele from the mother, thereby having a diploid (2n) number of homologous chromosomes.
Answer:
D
Explanation:
What would happen if gametes were not haploid?
A. If gametes were not haploid, the offspring would have half the number of chromosomes it is supposed to have.
B. It gametes were not haploid, the offspring would have double the number of chromosomes it is supposed to have.
c. If gametes were not haploid, the offspring would be genetically identical to its parent.
D. If gametes were not haploid, the offspring would be genetically different from its parent.
Why is it important for a cell to perform checks after DNA replication?
A.
If errors are not removed from areas with a gene, then the resulting proteins could be affected.
B.
If errors are not removed from areas with a gene, then the resulting lipids could be affected.
C.
Errors in DNA replication that occur in any cell type will be passed to the offspring.
D.
Errors in DNA replication that occur in any cell type will always result in death of the cell.
Answer:
A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.
Explanation:
Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.
It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.
Answer:
A.If errors are not removed from areas with a gene, then the resulting proteins could be affected.

Which muscle of the pectoral girdle helps during forced inhalation in breathing?
Answer:

ANSWER IN YOUR OWN WORDS
what is a destarched leaf
Answer:
Destarching occurs in a plant when a part of a plant is "deprived of starch, as by translocation". It is also the process of eliminating starch reserves in a plant for experiments concerning photosynthesis. ... Due to the lack of photosynthesis in this place, stored starch is used up, thus the plant is destarched.

TWO factors that would increase the carrying capacity for a secondary consumer. Explain
u are awesome have a good day
Explanation:
ok mam u are awesome that is nice
Which organism is the secondary consumer
Aspen--> Rabbit--> Snake--> Hawk
uhhhh....thanks, to uh whoever answers dis....yeah...
Answer:
The organism that is the secondary consumer is Snake.
The Snake is the secondary consumer because secondary consumers are animals that eat herbivores. For example, the snake eats rabbits and rabbits are herbivores.
concentration:
the amount of a substance within a _______ of another
substance
Answer:
Volume
Explanation:
In chemistry, the CONCENTRATION of a solution is the amount of a substance present within a volume of another substance. In other words, the concentration refers to the amount of a solute dissolved in a particular volume of a solvent to make a solution.
Concentration can be expressed in mass per volume i.e. g/cm³ or mol per volume i.e. mol/L or mol/dm³ etc. The amount of a substance is measured in Mass or mole, while the volume of a substance in Litres (L).

Read the following excerpt from "Woman Who Helped Hide Anne Frank Dies at 100" by Teri Schultz. SCHULTZ: Gies said she took the diary out of the desk where she'd saved it and she handed it to Otto Frank with the words: this is the legacy of your daughter Anne. She had never read a word of it, and in fact, could not bring herself to do so until after Otto Frank published the diary in 1947, two years after Anne's death. In this excerpt, Schultz is researching what Miep Gies told Stamberg. paraphrasing what Miep Gies told Stamberg. copying what Miep Gies told Stamberg. listening to what Miep Gies told Stamberg.

Poor land management can threaten an ecosystem's {Blank}
though habitat destruction, population
fragmentation, and resource loss, reducing its number of
species.
Answer:
Biodiversity
Explanation:
Given that Biodiversity is a biological term that describes the varieties and healthy nature of an ecosystem. It shows the presence of various species of plants and animals in an ecosystem. It can be affected by climatic changes or human interactions that are considered destructive.
Hence, Poor land management can threaten an ecosystem's BIODIVERSITY through habitat destruction, population fragmentation, and resource loss, reducing its number of species.

in your own opinion how do the three major processes of heat transfer affect the temperature of the earth
Answer:
In my opinion, the processes of heat transfer assume a significant function in the energy and radiation equilibrium of the earth temperature framework. Down welling radiation causes warming of the earth's surface because of direct daylight ingestion and furthermore because of the back radiation from the climate, which is the source term of the so intensely examined air nursery or Barometrical warming impact.
Upward radiation also adds to cooling and guarantees that the retained energy from the sun and the earthbound radiation can be delivered back to space and the world's temperature can be settled.
Explanation:
For every one of these processes, especially, the association of radiation with infrared dynamic atoms is of significance. These particles emphatically retain earthbound radiation, produced from the world's surface, and they can likewise be energized by some warmth move in the climate. The consumed energy is re-radiated consistently into the full strong point yet somewhat additionally re-assimilated in the environment, so the radiation underlies a persistent collaboration and change measure over the engendering distance.
In spite of the fact that the fundamental relations for this collaboration of processes of heat transfer, Radiation with atoms are now notable since the start of the earlier century, up to now the right utilization of these relations, their significance, and their ramifications for the environmental framework are examined conflicting in the network of atmosphere sciences.

Define "Fracking" and ways it can alter/upset the water cycle.
Answer:
Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. If the borehole is not properly cased to stop leaks, the fracking water can escape into the aquifer
