Answer:
The bloodstream carries glucose-a type of sugar produced from the digestion of carbohydrates and other foods to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen. Insulin , glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range.

Why do gymnosperms and lower vascular plants lack companion cells?
Answer:
Gymnosperms and lower vascular plants have sieve cells as their sieve elements, while sieve tubes are characteristic of flowering plants angiosperms. In gymnosperms, typical companion cells are lacking in the phloem. In gymnosperms, generally the xylem contains only tracheids. Vessels are absent.

What happens to DNA once transcription is done?
Answer: Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. ... RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Once transcription is completed, the newly synthesized RNA molecule called messenger RNA (mRNA), undergoes further processing and then moves on to the next step in gene expression, which is translation.
In eukaryotic cells, the mRNA molecule undergoes several modifications before it is ready to be translated into protein. These modifications include the addition of a protective cap structure at the 5' end of the mRNA, the addition of a poly-A tail at the 3' end, and the removal of non-coding regions called introns through a process called splicing. These modifications are important for the stability, transport, and efficient translation of the mRNA.
Once the mRNA is fully processed, it is transported out of the nucleus and into the cytoplasm, where it encounters ribosomes. Ribosomes are cellular structures that facilitate the process of translation.
During translation, the mRNA is read by ribosomes, and the sequence of nucleotides in the mRNA is translated into a specific sequence of amino acids, forming a protein. This process occurs in the cytoplasm and is mediated by transfer RNA (tRNA) molecules that bring the appropriate amino acids to the ribosome based on the codons present in the mRNA.

1. A worker uses a board that is 4 m long to pry up a boulder. A small rock is used for a
fulcrum and is placed 0.5 m from the resistance end of the lever. Calculate the MA of the
I
board.
Answer:
7
Explanation:
Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.
Here the boulder is [tex]0.5\ \text{m}[/tex] from the fulcrum and the mass at the other end of the lever is [tex]4-0.5=3.5\ \text{m}[/tex] from the fulcrum.
So, mechanical advantage is given by
[tex]MA=\dfrac{3.5}{0.5}\\\Rightarrow MA=7[/tex]
So, mechanical advantage of the board is 7.

2. How can dominance and expression of alleles explain the differences between these fraternal twins?
Answer:
Fraternal twins are from two seperate eggs.
Explanation:
The first part of the question is missing but any difference between fraternal twins can be explained by the fact that two seperate eggs are fertilized during the pregnancy so they have different genomes which leads to having different dominance of different genes and this leads to different expressions of this genes.

Identify the statement below that is NOT a principle of evolution.
O Populations evolve, individuals do not
O Negative adaptations will become more common in a population
O Variations occur naturally within a population
O Adaptations help individuals compete successfully for survival
B) negative adaptations will become more common in a population
negative adaptations will become more common in a population.
What is Evolution?According to the idea of evolution in biology, the many species of plants, animals, and other living things on Earth descended from earlier species, and their recognizable differences are the result of changes made by subsequent generations.
More than 2 million species of organisms already in existence have been recognized and documented; many more are still undiscovered, with estimates ranging from 10 million to 30 million.
The amazing variability in size, form, and mode of existence, from tiny bacteria with a diameter of less than a millionth of a millimeter to majestic sequoias with a height of 100 meters, is as astonishing as the figures.
Therefore, negative adaptations will become more common in a population.

Which structure pumps out excess water and wastes?
Answer:
The contractile vacuole pumps out excess water and wastes.
Cells have a particular organelle that pumps out excess water and other wastes from the cell. Contractile vacuole serves this purpose.
The protozoan cell contains an organelle or subcellular structure called the Contractile Vacuole. It is a spherical, transparent, translucent, pulsating single-cell organelle. Previously, it was referred to as a pulsatile or pulsating vacuole. It is encased in a unit membrane, floats in the cytoplasm, and is filled with watery fluid. It is a vacuole that constricts and expels water from the cell, as its name suggests. It frequently stretches and shrinks. While water is expelled from the contractile vacuole as it expands, the contractile vacuole contracts, causing water to collect inside the organelle. The contractile vacuole is the protozoan unicellular organism's kidney. It shows the rhythmic systolic and diastolic movements.
Therefore, Contractile vacuole pumps out excess water & wastes.
