Answer:
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Which two systems work together to make sure that all your cells get oxygen and get rid of carbon dioxide?
circulatory and respiratory
circulatory and digestive
muscular and skeletal
muscular and respiratory
For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.
Where does the filtrate go from the distal convoluted tubule? a) Loop of Henle b) Collecting duct c) Proximal convoluted tubule d) Bowman's capsule
After passing through the distal convoluted tubule, the filtrate drains into the collecting duct. Thus, B would be the correct answer.
how does diffusion impact the toxicity of an environment?
Answer:
A chemical's physical state and the route of exposure influence toxicity. ... Inhalation exposure also allows some rapid entry into the systemic circulation, causing toxic effects distant from the entry route.

What is the difference between backbone and spinal cord?
Explanation:
Spinal Cord is the tube-like structure which consists of bundles of nerve fibers. It is covered by the meninges and is surrounded by the cerebrospinal fluid.
Backbone or the spinal column is the central axis of the skeleton in all vertebrates. In a newborn human, there are about 33 bones that make up the spinal column. By the time the newborn becomes an adult, the number of bones reduces to 24 as they fuse during normal growth and development.
Moreover, the spinal cord is protected by the spinal column. In this article, we shall explore more differences between the two:
Difference Between Spinal Cord and Backbone
Spinal Cord
Backbone
Composition
Made up of bundles of nerve fibers
The backbone is made of bones called vertebrae
Function
Spinal cord acts as pathways for communication between the brain and the body
The backbone serves to provide structural support as well as support the body’s weight. It is also tasked with protecting the spinal cord
Segments
The spinal cord forms 31 segments, which are divided into 8 cervical nerves, 5 lumbar nerves, 12 thoracic nerves, 1 coccygeal nerve and 5 sacral nerves
The backbone can be split into 5 major segments – the cervical spine, the thoracic spine and the lumbar spine, sacrum and coccyx. Cervical spine is made up of 7 bones called vertebrae. Thoracic spine has 12 vertebrae and the lumbar spine and 5 vertebrae

A cell with a diploid number of 2n = 8 undergoes mitosis. How many
chromosomes will EACH new cell have?
Answer:
8
Explanation:
Mitosis, a type of cellular division, involves the division into two daughter cells that are genetically identical to the parent cell. They are genetically identical in the sense that the daughter cells contain the exact same DNA sequence as the parent cell and also, the chromosome number does not change.
In this case, a cell is said to have a diploid number (2n) of 8 chromosomes. It will therefore, undergo mitosis to produce two daughter cells with 8 chromosomes each. For this reason, mitosis is called MULTIPLICATION DIVISION.

How can I write this in my own words⁉️
Answer:
Humans travel at a way slower speed than Earth plates traveling. But for the earth's plates to travel, it will taake a very long time for it to travel great distances. In tens of millions of years, the Mesosaurus fossils moved apart gradually. Seafloor spreading also happens very slowly and gradually.
Explanation:
what types of interactions regulate gene expressions
Answer: Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.

Problem 1
In dust bunnies, short ears are dominant to long ears. If a heterozygous female mates
with a long ear male, what are the chances their offspring will have short ears?
Answer:
50% or 1/2
Explanation:
This question involves a single gene coding for ear length in dust bunnies. The allele for short ears (S) are dominant to the allele for long ears (s). This means an heterozygous individual (Ss) will possess short ears.
According to this question, If a heterozygous female (Ss) mates with a long ear male (ss), the parents will produce gametes as follows:
Ss - S and s
ss - s and s
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Ss, Ss, ss, ss
- Ss (1/2 or 50%) offsprings will have short ears.
- ss (1/2 or 50%) offsprings will have long ears.

2. Something an organism does in response to a change in its environment 2 poin
to ensure its survival. *
Structural adaptation
Functional apadtation
Behavioral adaptation
Mutual adpatation
Answer:
3. Behavioral adaptation
Explanation:
The environment is what helps everything live, which means that its behavior changes according to it's surroundings, such as a bear hibernating in the winter, that is its behavior because it is cold, and food is very hard to find, unlike in the summer and spring where food is everywhere, so the only choice the bear has is to collect as much food as it can before winter comes in.
5. What type of mutation has occurred in the strands provided. *
Original strand: ATGCATGGAC
Mutated strand: ATGGAIGGA C
Insertion
Substitution
Deletion
Framshift
Answer:
It is a substitution of a cytosine with a guanine

Explain how phospholipids form cell membranes.
Answer:
Phospholipids are able to form cell membranes because the phosphate group head is hydrophilic (water-loving) while the fatty acid tails are hydrophobic (water-hating). They automatically arrange themselves in a certain pattern in water because of these properties, and form cell membranes.

how china is taking jobs from the world?
The current U.S. administration sees China as the United States’s principal global rival, and it has effectively declared economic war on the country. Its justification for this is largely that China is (1) stealing American jobs and (2) pirating American intellectual property. Data collected by the Long US-China Institute suggest that China is far less guilty of these crimes than many policymakers and commentators would have us believe.
As the exhibit just below shows, consumer incomes in both countries have enjoyed continuous growth in purchasing power since 1985. Only two years of decline are discernable in the U.S. trendline: 2008 and 2009, coinciding with the 2008/9 recession.
