"Using the three points of the cell theory, explain how humans and bacteria are similar."

Answers

Answer 1
1. They are made of cells

2. They are the basic unit of structure and function

3. They are cells produced from other cells
Answer 2

Answer:

Cell theory was first developed by Scheldien and Schwann.  The cell theory was follows by all the living organism except viruses. The cell theory explains that eukaryotes and bacteria are similar.

Both the bacteria and humans are made of more than one cells. Cells acts as the structural and functional unit of the humans and bacteria. All the important functions of the bacteria and humans are done by cells. The living cell of the bacteria and human are arise from the pre existing cell.

Estimate how much the brain would swell due to osmosis if the concentration of the cerebrospinal ±uid fell to 280mm. in other words, ³nd what the new volume

Answers

Since the average osmotic pressure of the brain is 300mM and the concentration of the solution is 280mM, that means there is 20mM difference between the brain cells and CSF. This will induce osmosis and cause water to move from the CSF into the brain until the concentration becomes same. Assuming brain volume is 1200ml and the CSF constantly replaced., then the estimation of fluid should be: 20mM/300mM * 1200ml= 80 ml
If it made percent it should be: 80ml / 1200ml= 6.67%
Final answer:

Estimating how much the brain would swell due to a drop in cerebrospinal fluid concentration to 280 mm involves understanding osmosis and brain-CSF osmotic balance, which is crucial for preventing conditions like hydrocephalus. The exact new volume would need medical evaluation.

Explanation:

The question concerns the phenomenon of brain swelling due to osmosis caused by changes in the concentration of cerebrospinal fluid (CSF). When the concentration of CSF falls, such as to 280 mm, water can flow into the brain cells due to osmotic imbalances, potentially leading to a condition like hydrocephalus. However, estimating the exact new volume of the brain due to osmosis requires sophisticated medical instruments and knowledge of osmotic pressure in the brain's environment. Normally, the pressure in the CSF ranges from 5 to 12 mm Hg, and deviations from this range can affect the brain's volume and pressure dramatically.

For example, if the gauge pressure in the fluid surrounding the brain increases significantly, it can lead to an increase in the outward force on the skull, even causing the skull to grow abnormally large in infants with hydrocephalus. In adults, a reduction in the CSF concentration can cause severe headaches and damage due to the brain resting upon the skull.

The specific volume change due to a CSF concentration drop to 280 mm would vary based on individual circumstances and would require medical assessment to determine.

) when cells are broken open, dna is released from cells into solution. name at least two other macromolecules that are also released from the cells, and the places they are found in the cells.

Answers

Protein, nucleic acid, carbohydrate and lipid that are released from the cell.

Protein and nucleic acid are the two macromolecules that are also released from the cells when the cell is broken up because these two macromolecules are present in the cell and performs different types of functions that helps the cell in growth and development.

There are two more macromolecules are present such as carbohydrates and lipids in the cell that are also very important for cell so we can conclude that when the cell is broken, protein, nucleic acid, carbohydrate and lipid are released from the cell.

whats the relationship of the organelles of the endomembrane system

Answers

They all work together to package, label, and ship protein and molecules.
Final answer:

The organelles of the endomembrane system - the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles - interact and cooperate via direct contact or vesicle transfer. Their individual functions contribute to the overall function of the cell in terms of production, modification, transportation, and disposal of substances.

Explanation:

The organelles of the endomembrane system are interconnected through direct contact or by the transfer of membrane segments as tiny vesicles. The endomembrane system consists of the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, and vacuoles.

The nuclear envelope is contiguous with the endoplasmic reticulum, which manufactures lipids and proteins. These products are then sent to the Golgi apparatus in vesicles, which modifies them for their specific functions and addresses them for transport to their proper locations. Lysosomes contain enzymes that break down waste materials and cellular debris, while vacuoles are storage organelles that can hold a variety of substances.

A 7 kilogram cat is resting on top of a bookshelf that is 1 meters high. What is the cat’s gravitational potential energy relative to the floor ?

Answers

The equation of motion that is suitable for this situation is:
Potential energy = MgH, Where:
M = mass = 7
g = gravitational acceleration = 9.8 m/s
H = height = 1
Potential energy = mgh = 7 * 9.8 * 1 = 68.6.
Therefore, the gravitational potential energy relative to the floor is approximately 69 J.

How does the temperature affect enzyme function? use evidence from your data to support your answer?

Answers

If the temperature is too high, it can alter the structure of the enzyme and make it unable to bind to the substrate. But, if the temperature is too low the chance for the enzyme to collide with the substrate will be lower too. The enzyme works best in the highest temperature before its structure changed.
The data from the experiment should look like a bell. There is an optimal temperature for the enzyme and increasing/decreasing from that temperature will result in reduced reaction speed.
An increase in temperature will increase the reaction rate of enzymes. For instance, a 10 degree celsius rise in temperature will increase the activity of most enzymes by 50% to 100%. But too high temperature negatively affect enzymes and their functioning.

An allele is one of the alternative forms of a gene that governs a trait. If a fern plant is heterozygous for a particular trait, how can the alleles that control that trait be described? A. one dominant, one recessive B. two dominant C. three recessive, one dominant D. two recessive

Answers

"Hetero" means different. So the plant has two different alleles; one dominant and one recessive as in (A).

Answer:

The correct answer is A. one dominant, one recessive

Explanation:

A gene can have many alternative forms called alleles. These alleles can be present in homozygous condition or heterozygous condition. In homozygous condition chromosome contains two same forms of an allele of a gene. In heterozygous condition a chromosome contains two different forms of an allele of a gene.  

These alleles can be dominant or recessive. A dominant allele can be expressed in both homozygous and heterozygous condition, but a recessive allele will only express in homozygous condition.

So If a fern plant is heterozygous for a particular trait then it contains one dominant and one recessive allele because in heterozygous condition two different forms of allele is present. Therefore the right answer is A.
