Answer: Each lung is composed of smaller units called lobes. Fissures separate these lobes from each other. The right lung consists of three lobes: the superior, middle, and inferior lobes. The left lung consists of two lobes: the superior and inferior lobes. A bronchopulmonary segment is a division of a lobe, and each lobe houses multiple bronchopulmonary segments. Each segment receives air from its own tertiary bronchus and is supplied with blood by its own artery. Some diseases of the lungs typically affect one or more bronchopulmonary segments, and in some cases, the diseased segments can be surgically removed with little influence on neighboring segments. A pulmonary lobule is a subdivision formed as the bronchi branch into bronchioles. Each lobule receives its own large bronchiole that has multiple branches. An interlobular septum is a wall, composed of connective tissue, which separates lobules from one another.

How does seed formation take place in plant? explain.
Answer:
Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.

A. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Disulfide bonds
B. 3 base codon one the bottom, Amino acid attachment site on top, phosphate groups on the left and right sides
C.3 base codon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
D. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
Answer:
the answer is D 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
Explanation:
idfk know man, but thats the answer!
The option that correctly describes the tRNA's structure is D. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
tRNA stands for transfer ribonucleic acid. It interacts with the mRNA and aminoacids being a key element in protein synthesis.
The tRNA structure is:
Three base anticodon, one on the tRNA's bottom. They are three nucleotides that interact with a complementary mRNA codon. An amino acid attachment site on top where the specific amino acid for the anticodon attaches, later on, in the ribosome, together with the codon in the mRNA it adds the amino acid to the forming protein.Hydrogen bonds between tARN bases. These bonds give the tRNA its characteristic shape.In conclusion, the tRNA structure is anticodons, an amino acid attachment site on top, and hydrogen bonds between the bases.

If 30% of a DNA sample is composed of thymine nucleotides, what percentage of the DNA sample would be composed of cytosine nucleotides?
Answer:
20%
Explanation:
Pairing do occur between a purine and a pyrimidine base or a pyrimidine and a purine base where Adenine pairs with Thymine and Guanine pairs with Cytosine.
DNA(deoxyribonucliec acid) sample is usually compose of 100% nucleotide base,
Since 30% of the sample section is compose of thymine then Adenine the base pair will also be 30% this is because adenine will always pair with thymine and each will occur in equal quantity. Together, adenine and thymine compose 60% of the segment.
While the remaining 40% of the section is composed of guanine and cytosine pairs and since the two bases will be equal in quantity, 20% of the DNA section will be cytosine nucleotide.

Look at Scenario A below and select the correct Punnett Square that corresponds with the scenario. For all questions, the trait being studied is seed color - red seeds (R, dominant) and pink seeds (r, recessive). Scenario A: Parent 1: heterozygous Parent 2: pink
Answer: A
Explanation:
Heterozygous means it has both a recessive and a dominate allele so in this case it’d be shown as Rr. For a parent to appear pink, the genotype must be rr (because r is recessive and won’t show up in the parent if there’s a dominant allele to over lower it). The only option that shows an Rr and rr pairing is option A

What is carbon emissions responsible for?
Answer:
Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.
Explanation:
What can Carbon do?
Carbon emissions affect the planet significantly, as they are the greenhouse gas with the highest levels of emissions in the atmosphere. This, of course, causes global warming and ultimately, climate change. Carbon dioxide is released into the atmosphere when fossil fuels — coal, natural gas, and oil — are burned.
Which structure helps fish remove oxygen from the surrounding water?
Answer:
Gills
Explanation:
In order to remove oxygen from the water, they rely on special organs called "gills." Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages.

A. 100
B. 75
C. 50
D. 25
E. 0
Answer
75% chance
Explanation:
The dominant and recessive are the terms used to explain the phenotypic traits and genetic makeup of an organism. The cross between a heterozygous species will result in a 75% chance of the species expressing a dominant phenotype.
The correct answer is:
Option B. 75%
The heterozygous condition refers to the one dominant and one recessive allele, whereas purebred is the condition in which both alleles are either recessive or dominant.
The dominant alleles are always expressed in purebred and heterozygous conditions.
The recessive alleles are expressed in purebred conditions only.
In the given attachment, consider the cross between round shaped-seeds in heterozygous conditions.
Thus, the chance of progeny will have round-shaped seeds is 75%.

Is it varration , overpopulation or adaption On average, sea turtles lay about 110 eggs in a clutch. However, only a fraction of the baby turtles make it to the ocean. Then, an even smaller number have offspring of their own.
Answer: this is adaptation, but not in the way suggested in the question.
Explanation:
The question is suggesting that the 1% or so of turtle hatchlings that make it to maturity are the result of a variation that gives a selective advantage. This is not so. The only thing being selected for is sheer luck. The underlying adaptation is that all eggs hatch within a short period, so that predators are overwhelmed by numbers and some offspring by chance make it to the water, still dangerous, but less so than the sand. After the hatchlings reach the sea chance will still be a factor, but it is at this stage that natural selection may operate on advantageous variations.
There are two reproductive strategies, common to plants as well as animals. Turtles represent one of those strategies, which is to invest resources to produce large numbers of immediately self-sufficient offspring so that at least some will survive. The other strategy is to produce one or few offspring and invest resources in protecting and feeding it or them until self-sufficient and capable of surviving to maturity.
These are adaptations which are selected for because they confer advantage for the species concerned. One or the other may be the better solution depending on the species. Mammals, for example, invest in the latter strategy.
What are two genotypes that could produce a dominant phenotype?
Answer:
A homo-zygous dominant genotype and a heterozygous genotype
Explanation:
A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.
___ of the greenhouse effect is a bad thing. Since there are more and more greenhouse gases in the atmosphere more ___ is trapped which make the earth ___. This is called ___
Answer:
1. Increase/occurrence
2. Heat
3. Warm
4. Global warming
Explanation:
Greenhouse effect is the process whereby heat is trapped by certain gases in the atmosphere called GREENHOUSE GASES e.g. carbon dioxide (CO2). Greenhouse gases have the ability to trap heat, hence, their increase in the atmosphere becomes a major concern as it starts becoming a bad occurrence.
An increase in the greenhouse gases in the atmosphere means more heat will be trapped, thereby, inducing the Earth to become WARM. This process where the Earth's temperature rises as a result of greenhouse effect is called GLOBAL WARMING.
