"We may not know about all organisms present in the ancient world since not all organisms on Earth can be fossilized". The best statement is that Organisms that have soft bodies decay before they fossilize.
What are the soft body animals?The animals represented via way of means of those newly found fossils, which include sponges, annelid worms, mollusks, and horseshoe crabs, lived at some stage in the Ordovician length among 480 million and 472 million years ago, making them the oldest ever found at some stage in this length.
For a soft-bodied animal to be fossilized, its frame should be blanketed from decomposition. The frame is typically uncovered to air and water with quite a little oxygen, so it decomposes rapidly. The animal is probable to be fossilized best if it's miles buried quickly after it dies (or whilst it's miles buried may be fossilized.

Fewer storms
Habitat loss
Increased oxygen levels
Severe weather increase
The option that is a direct result of deforestation is habitat loss. Details about deforestation can be found below.
What is deforestation?Deforestation is the process of destroying a forest and replacing it with something else, especially with an agricultural system.
Deforestation is often caused by the need to build non-agricultural resources.
However, destroying forest is synonymous to destroying the habitats of living organisms.
Therefore, the option that is a direct result of deforestation is habitat loss.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.
A microscopic image of staphylococcus aureus is shown.
Which immune system component initially results in the inflammation and responds quickly when Staphylococcus aureus enters the bloodstream?
complement system
phagocytes
Langerhans cells
B lymphocytes
The complement system will work first in the given scenario of Staphylococcus aureus infection, i.e., option A.
What is a complement system?The complement system, also known as the complement cascade, is an immune system component that improves (complements) antibodies' and phagocytic cells' ability to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.
In the given scenario, when Staphylococcus aureus enter the body through an injury or broken skin, and get into the bloodstream then the complement system initiate the phagocytosis.

Anyone know how to do this?
Answer:
The ones in bold are the answers. I really hope this helps you.
Explanation:
Blood sugar is too high. Pancreas releases insulin to stimulate the liver and store glucose to break down sugar from the blood and store it as glycogen or glucose. Blood sugar levels decreases.
Blood sugar level is too low. Pancreas releases glucagon to stimulate the glucose production in the liver and maintain adequate plasma glucose concentrations to convert stored glucagon and fat back into glucose to be released in the blood. Blood sugar levels increases.

The change an ecosystem experiences over time
The change in ecosystem experiences over time.
In simpler words, the process in which there is a change in species, as well as habitat, occurs over some time.
Please describe the process of natural selection in your own words by using an example.
Answer:
natural selection is animals slowly adapting to its environment
an example is giraffes, giraffes with longer necks will be able to consume more food than giraffes with shorter necks as they they can reach for the leaves on trees. over time the giraffes with shorter necks become extinct and giraffes with longer necks still remain.

A mouse had a gene sequence of GTT coding for leucine, an amino acid.
mutation in this gene led to the formation of GTG. However, the amino acid formed was leucine, despite the mutation. This is a
mutation for the mouse.
The mutation that occurred in the mouse is a silent mutation since it does not affect the amino acid sequence in the protein.
What is a mutation?A mutation is a change that occurs in the sequence of nucleotides in the DNA of organisms.
A mutation can either have deleterious effect on the organism or have no effect at all. Mutations that do not have any effect on the organism are known as silent mutations.
Silent mutations do not affect the sequence of amino acids that make up a protein.
Therefore, the mutation that occurred in the mouse is a silent mutation since it does not affect the amino acid sequence in the protein.

What does the sequence of amino acids tell you about an organism and its relationship to another?
Would they be similar or different? Why?
Answer: Because the amino acid sequence of a protein is determined by its DNA sequence, a gene shared by two closely related animals should have amino acid sequences that are similar, if not identical. Because closely related species split from one another very recently in the evolutionary timeline, this is the case.

During ____________ , an enzyme removes a ____________ functional group from the monomers of one organic molecule and a hydrogen from another monomer, linking monomers together to form a ____________ . This chemical reaction also forms ____________ .
During dehydration synthesis, an enzyme removes a hydroxyl functional group from the monomers of one organic molecule and a hydrogen (H) from another monomer, linking monomers together to form a polymer. This chemical reaction also forms water molecules as byproducts.
An enzyme removes a hydroxyl (-OH) group from one monomer and a hydrogen (H) from another during dehydration synthesis, allowing the monomers to form a polymer. This mechanism bonds monomers covalently and produces water molecules. Complex biological components including proteins, nucleic acids, and carbohydrates depend on dehydration synthesis.
Eliminating water molecules strengthens chemical connections, making it easier to assemble bigger structures from smaller components. This response aids energy storage, structural stability, and information flow in living things.

Choose 1 answer:
(A) the skin is made up of tissue.
(B) the skin is made up of different tissues that carry out the same function.
(C) the skin is made up of tissues with different functions that work together.
Answer:
A
Explanation: the skin is made up of tissue
The skin is made up of tissues with different functions that work together. So, the correct option is (C).
What is Skin?Skin is defined as the largest organ of the body where skin and its derivatives such as hair, nails, sweat and oil glands form the integumentary system. The main function of the skin is protection which protects the body from external factors such as bacteria, chemicals and temperature.
The skin is made up of water, proteins, fats and minerals that protect the body from germs and regulate body temperature. Skin nerves help to feel sensations like hot and cold.
It is made up of three layers, the epidermis, dermis and hypodermis which are anatomically distinct. Its structure is made up of a complex network that serves as the body's initial barrier against pathogens, UV light and chemicals, and mechanical injury.
Thus, the skin is made up of tissues with different functions that work together. So, the correct option is (C).
