Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A membrane is a thin layer which forms the wall of the cell and typically controls what leaves and enters the cell.
Some of the effects of various biological conditions on membrane physiology are;
1. Makes RMP (Resting Membrane Potential) Less Negative: this simply means that it decreases RMP;
Decreased concentration of leaky potassium channels in the membrane. ATP stores are declining through mitochondrial poison (arsenic). Increased concentration of leaky sodium channels in the membrane.2. Influences the Ability of the Cell to Repolarize;
Voltage regulated potassium channels are blocked. Acetylcholine esterase concentration is decreased.3. Influences the Ability of the Cell to Depolarize;
The size of the synaptic cleft is increased. Hyperhydration (high water concentration in ECF). Release of excitatory neurotransmitter by a presynaptic input is blocked. Hyponatremia (low ECF sodium).Neurotransmitter synthesis is compromised due to Golgi dysfunction in the presynaptic neuron.PLEASE ANSWER ASAP FOR BRAINLEST!!!!!!!!!!!!!!!!!!!!

Which hypothesis do the similarities in the bone arrangements support?
a. These organisms are members of the same species.
b. These organisms may have descended from the same ancestor.
c. These organisms have adaptations to survive in different environments.
d. These organisms all contain the same genetic information.
Answer:
B
Explanation:
A similarity in the arrangement of bones in organisms can be hypothesized to be an indication of the organisms descending from the same ancestor.
The similarity in the arrangement of bone in different organisms is one of the morphological evidence used to support the theory of organic evolution which says that all living organisms are of the same descent with modification from common ancestors.
The similarity in the arrangement of bones falls under homology. Homologous organs are similar in structures but different in functions. For example, the pentadactyl limbs of vertebrates. Mammals, birds, reptiles, and amphibians all have limbs that are built on a five-digit plan but the functions of the limb vary within and among different groups of vertebrates.

If the fraction of base pairs devoted to protein-coding genes is the same as the fraction of the total genes that they represent, what is the average number of base pairs per protein-coding gene
[tex]\mathbf{Here \ is \ the \ missing \ part \ of \ the \ question} \\ \\ \mathbf{The \ genome \ of \ Escherichia \ coli \ consists \ of \ 4380 \ genes, \ encoding \ 4290} \\ \\ \mathbf{ proteins, \ in \ jus t \ 5175720 \ base \ pairs. \ What \ percent \ fraction \ of\ the} \\ \\ \mathbf{ Escherichia \ coli \ genes \ encode \ proteins?}[/tex]
Answer:
1182
Explanation:
From the information given:
Number of present genes = 4380
the total no. of protein-encoding = 4290
Total no. of base pairs = 5175720
The percentage fraction of genes encoding the protein is;
total no of protein-encoding gene/total no of present genes
[tex]\mathbf{\dfrac{4290}{4380} = 0.9795}[/tex]
= 97.95%
The average number of base pairs per protein-coding gene is;
= total no. of base-pair/ no of present genes

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase. The complete cell cycle requires 24 hours. Match the average duration to the appropriate cell cycle stage in these cells. M phase prophase metaphase telophase 4.8 hours 14.4 minutes 2.4 hours 36 minutes
Answer:
M phase: 4.8 hr
Prophase: 2.4 hr
Prometaphase: 0.72 hr
Metaphase: 0.24 hr
Anaphase: 0.84 hr
Telophase: 0.6 hr
Explanation:
Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:
M phase: 40/200 = 0.2 x 24 hr = 4.8 hr
Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr
Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr
Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr
Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr
Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr

2. Honey Bees may be headed for extinction.
Why do you think this is happening? (Things
to think about: habitat destruction, erosion,
pollution, invasive species, human impact.)
Answer:
Well the most common is habittat destruction. With the number of humans only growing, more land is needed and habitat desturctions occur. Lack of food is also a problem, as some crops don’t grow as much so the bee’s food source is smaller which leaves thousands dead. Also if the food source doesn’t run out, there are pesticides sprayed and the bees will die if eaten one which the chemical properties in a pesticide will kill. Also if not used, littering, if you dump it into a water source, the water gets contaminated and the bees could die from that, or the water spreads ano the flower would receive this chemical property, which could kill the Bee’s food source, or the flower doesn’t die but when the bees consume it, the bee will die.
Answer:
honey bees Extinction types are parasites ,habitat loss ,and cell phones. but there two main types of parasites that are harming the honeybees are Vero mites and tracheal

Planting trees reduces destruction to homes and crops by serving as ___ during typhoons and storms.
a. Shelter
b. Income
c. Feltilizers
d. Windbreakers
Answer:
Windbreakers
Explanation:
Income and fertilizers have nothing to do with it, so those are not it. Then there are shelter and windbreakers. It kind of acts as a shelter, but mainly it protects crops and homes by acting as a windbreaker. If it was shelter, that would mean that the crops would mainly be planted under the trees to reduce damage from storms and typhoons. Therefore, it is D) Windbreakers.

HURRRRYYYp
Answer:
The first statement is true, while the second statement is false.
Explanation:
Every living organism needs a particular amount of food in order to be able to survive. Each species though has its own different requirements, and there are great variations that occur because of size, lifestyle, is the organism cold-blooded or warm-blooded, etc.
In this case, we have to examples. In the first one, a single mouse needs 4 square meters of grass in order to stay healthy. In order to get the amount of grass needed for fifty mice, we just need to multiply the number of mice by the amount of grass needed for one of them:
50 x 4 = 200
We got 200, meaning that 200 square meters of grass will support a population of 50 mice.
In the other case, a single snake needs 10 mice in order to stay healthy. To get a result how many mice are needed for 10 snakes, again we just need to multiply the number of snakes by the number of mice a single snake needs:
10 x 10 = 100
We got 100, meaning that 10 snakes need 100 mice in order to stay healthy.

In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *
a solar eclipse
a lunar eclipse
a spring equinox
a summer solstice
Answer:
a lunar eclipse
Explanation:
The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

Answer:
Robert Hooke.
Explanation:
Robert Hooke is a British scientist and he was the scientist that looked at cork and used the term "cells" to describe what he saw in 1665.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include cell membrane, nucleus, golgi apparatus, cytoplasm, ribosome, lysosome, chromosome, etc.
Answer:
