Blood pressure is highest in the arteries closest to the heart and lowest in the veins.
Veins are blood vessels located throughout your body that collect oxygen-poor blood and return it to your heart. modes are part of your circulatory system. They work together with other blood vessels and your heart to keep your blood moving. modes hold utmost of the blood in your body.
Arteries, a critical part of your cardiovascular system, are blood vessels that distribute oxygen-rich blood to your entire body. These tube- suchlike vessels and the muscles inside them insure your organs and apkins have the oxygen and nutrients they need to serve.

Why does the grass look green under sunlight and black under the moonlight? ( explain in the process of filtering light )
In a eukaryotic cell, which of the following processes directly involves DNA?
The provided question lacks the options, however, the options associated with the question is as follows;
A. translation
B. cellular respiration
C. active transport of ions
D. replication of chromosomes
Answer:
The correct answer is - D. replication of chromosomes.
Explanation:
During every cell division, either meiosis or mitotic the chromosomal DNA present in the nucleus is needed to be duplicated and the process that involves the duplication of this chromosomal DNA is known as replication of chromosome which takes place during the interphase of the cell division.
All other processes mentioned in the options are not involved or directly not involved in the processes. Translation involves the mRNA in the cytoplasm to produce amino acids with the help of ribosomes. Cellular respiration involves mitochondria and does not require DNA in the process.
Which parts of photosynthesis occur in the thylakoid membranes of the grana? Check all that apply.

How do solar thermal generators work?
A)
They block high-angle sunlight but allow the penetration of low-angle sunlight.
B)
They use electric pumps to circulate air, water,and other fluids to places where heat is stored and then pumped to where energy is used.
C)
They use flat glass-covered plates over a black background which takes in solar radation and emits heat.
D)
They use solar cells to convert sunlight directly into electricity.
E)
They use sunlight to boil water and run steam-driven systems.
Answer:
D
Explanation: Best Choice
Answer:
E.
Explanation:
Solar thermal power/electric generation systems collect and concentrate sunlight to produce the high temperature heat needed to generate electricity. ... The steam is converted into mechanical energy in a turbine, which powers a generator to produce electricity.

Explanation:
7. UGG 8. GAU 9. AUA 10. phenylalanine 11. aspartate 12. isoleucine
During translation, tRNA adds the correct amino acid to the growing protein, following the mRNA codon sequence. Tryptophan, Lysine, Leucine, Tyrosine.
What is translation?Translation is the stage in protein synthesis that follows transcription, and occurs in the cytoplasm.
When mRNA leaves the nucleus and moves to the cytoplasm, it meets a free ribosome that is the primary structure for protein synthesis. Ribosomes are composed of two subunits of rRNA associated with different tRNA that carries amino acids.
The ribosome reads mRNA in the 5' to 3' direction, and, according to the codons that are being readen in mRNA, tRNA transfers the correct amino acids to build the polypeptide chain.
Let us remember that the codon is the sequence of three nucleotides present in mRNA. The molecule carriesa a start codon and stop codons.
Each tRNA has two important sites. One of them is the antidocon that couples with the codon of the mRNA molecule. The other site couples with the coded amino acid.
The protein is synthesized from the amino terminus to the carboxy terminus.
In the example,
DNA mRNA tRNA Amino Acid
ACC UGG ACC Tryptophan
TTC AAG UUC Lysine
GAT CUA GAU Leucine
ATA UAU AUA Tyrosine

*lf a strand has 35% adenine, what percent will be cytosine?
Answer:15% cytosine
Explanation:We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.

Which statement best explains how respiration and photosynthesis are related to one another?
A Respiration requires water that is given off during photosynthesis.
B. Photosynthesis requires oxygen that is given off during respiration.
C. Photosynthesis gives off carbon dioxide that is required for respiration
D. Respiration gives off carbon dioxide that is required for photosynthesis
Answer: D
Explanation:
photosynthesis - takes in water, energy from the sun, and carbon dioxide and releases oxygen and glucose (sugar)
respiration - takes in glucose and oxygen, and releases water and carbon dioxide and energy
they are basically the opposite

Archaebacteria and eubacteria are classified into different kingdoms, but at one time they were both classified in the Kingdom Monera. Which statement best describes why the classification of these organisms was changed?
A. The kingdom became too large and had to be made into two smaller kingdoms.
B. New biochemical data showed different evolutionary relationships within the kingdom
C. The archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
D. Chromosomal analyses indicated a new genetic combination had arisen within a certain organisms in the kingdom.
Answer:
I think the option C is correct
The statement best describes the classification of these organisms was changed is the archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
What are the characteristics of Archaebacteria?Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.
Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences.
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.
