Why do fossils that paleontologists find represent only a partial picture of life in the past?
Answers
Answer:
Because we cannot see some animals properly like jellyfish as their tissue is too soft, and feathers or for can often not make an imprint on fossils.
Explanation:
Answer:
Fossils: They are remains of animals or plants in the past that were somehow preserved and buried under the earth's crust.
One fossil can only give us a glimpse into the history of the time that particular animal or plant lived or breathed on the earth. For example, a fossil remains of a particular species of dinosaur would only provide information of the time when that species lived on earth and other information related to that particular time. Fossil remains of dinosaurs would not give us information on the time during the ice age or any other time in history.Explanation:
The study of various fossils can give us information about the development and evolution of living organisms over time but there are limitations to it.It may happen if we compare the fossil remains of an organism that existed billions of years ago we may find a time gap where there is no fossil evidence found so it creates a loop in information.Also, the process of fossilization is complex and long. Many species of the past became extinct without fossilization so we can never get information related to those extinct species.Thus, because of this reason we can say that fossils don't provide us with complete information about the past.For more information:

2. Gene
3. Chromosome
4. Genome
Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.
What is Chromosome?Chromosomes are the thread-like structure made up of protein (histones) and a single molecule of DNA which carries all the genetic information in it. It is located in nucleus.
Human have 23 pairs of chromosomes including pairs of 22 chromosomes (i.e. Autosomal Chromosomes) and 1 pair of Sex Chromosome (XX or XY).
Each pair contain two Chromosomes inheriting from the parents, half from mother and another half from the father.
Each chromosome have a point which is constricted in the middle known as Centromere, which divides chromosomes into two arms i.e. short arm “p” and long arm “q”.
Thus, Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.

In order to detect an odor, molecules must first dissolve in the ____________ before they bind to the receptor sites of the ____________ .
Answers
For an individual to detect an odor then molecules must first dissolve in the
mucus before they bind to the receptor sites of the olfactory hairs.
The nose is the organ responsible for smelling and it possesses key
components such as the mucus found in the olfactory epithelium and
receptors found in the olfactory hairs for processing the type of smell to the
brain.
When individuals inhale substances, they are dissolved in the mucus to aid
their binding to the receptors and their subsequent relay of the signal to the
brain for processing.

The main structural distinction between the left atrium and the right atrium is that the left atrium has the _____, and the right atrium does not.
a. auricle
b. pectinate muscles
c. cardiac muscles
d. chordae tendinae
Answers
Given our understanding of cardiac anatomy, we can confirm that the main structural distinction is that the right atrium has the pectinate muscles, while the left one does not.
Firstly, we must address that there is a wording issue with the question. In reality, it is the right atrium that contains the pectinate muscles. The remaining options either correspond to both atrium, or neither.
The auricle is another word for ear. This is a cavity present on both the right and left atrium which allows them to extend their blood carrying capacity in situations of need. This option cannot be correct for the question since both atria possess one.
As for options b and c, cardiac muscle is present in the entirety of the heart. Cardiac muscle is the muscular cells that make up every wall and cavity of the heart and allow it to complete its unique function. Chordae tendinae, are fibers present in the ventriculus that attach the walls to the tricuspid valve, these are not present in either of the atria.
Therefore, we can confirm that though the wording is off, the intended correct answer is pectinate muscles, given that the right atrium is characterized by their presence, whilst the left atrium contains few, if any, of these muscles.

the following statements best describes how vaccines work?
Group of answer choices
A. Antibodies in the vaccine provide the body with nonspecific immunity to an antigen.
B. Fever and swelling develop which is the first response in killing a pathogen.
C. An inactivated or killed virus stimulates the body to develop specific immunity to that type of virus.
D. Heathy bacteria causes the body to release toxins which will protect the body if later exposed to different type of bacteria.
Answers
Answer: Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen itself or the blueprint so that the body will produce the antigen, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen.

Answers
The homologous structure to the forearm of humans is the leg of the horse.
What are homologous organs?Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.
The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.
Homologous organs have different functions in organisms.

The structure that is responsible for the governance of a cell is the DNA, which is located in the nucleus of the cell.
Explanation:
DNA: It is the genetic material containing genetic information.It is present in the chromosomes inside the nucleus. The genetic information of DNA is stored as code in the four nucleobases namely Adenine, Guanine, Cytosine, and Thymine. The most unique feature of the DNA is that it is self-replicated and makes similar copies of itself. DNA is a double helical structure found in all living organisms including some viruses.In Eukaryotes along with the nucleus, DNA is also present in Mitochondria and Chloroplasts.For more information:

The human heart, skin, intestines, and even our bones are slowly replaced over time, meaning that a limited amount of damage can be reduced. However, this doesn't extend to limbs.

Humans have stem cells, but they aren't readily available to assist in healing. Because most other mammals are similar, they aren't very good at regeneration. Amphibians and some fish have more readily available stem cells, which are usually rather good at regeneration.(please mark brainliest <3)

Answers
Answer: a thrombus
A thrombus may also form in your heart
A thrombus is a blood clot attached to the interior wall of a vein or artery, which is option a. So the correct option is option a, as thrombus formation occurs when blood coagulation factors are activated and form a clot within a blood vessel.
Thrombi can occur in veins (venous thrombosis) or arteries (arterial thrombosis). In veins, a thrombus can lead to deep vein thrombosis (DVT), which commonly occurs in the lower extremities. If a thrombus dislodges from its site of origin and travels through the bloodstream, it is called an embolus, and it can potentially cause an embolism in another location. So the correct option is option a.
