1. The body of a person or other mammal is a complex organism. The structure of the body has several levels of organization. Which of the following lists the structural levels of the body from smallest to largest? *
A. cell → tissue → organ → organ system → organism
B. cell → organ → organ system → tissue → organism
C. organ → organ system → cell → tissue → organism
D. organ → organ system → tissue → cell → organism
Answer:
the answer would be A.
Explanation:
this would be because a cell is the smallest living thing, after cells, tissues are the next smallest thing, then it is an organ, because different tissues make up an organ, then multiple organs will create an organ system, and multiple organ systems create an organism.
The structure of the body has several levels of the organization, and the sequence is cell → tissue → organ → organ system → organism, hence option A is correct.
What is the body structure of a complex organism?The human body's biological functions are preserved at several levels of structural organization. The following levels are included: chemical, cellular, tissue, organ, organ system, and organismal.
The lowest unit of life is a cell. A tissue is made up of a variety of unique cells. Organ systems are made up of related organs that are made up of tissues. A living thing or organ is made up of various organ systems.
Therefore, any organism's cell is its fundamental structural and operative unit. Multicellular organisms are made up of cells, tissues, organs, and organ systems, which are composed of groups of similar cells, tissues, organs, and organ systems.

how does the Digestive system help maintain homeostasis?
In your answer, include the most important organ(s) (list at least 2) and include what they do to make the system work. It must include at least 3 full sentences
Answer:
The bacterial flora in the intestines are essential to homeostasis in the body, they not only break down food so the nutrients can be absorbed, they produce vitamins like biotin and vitamin K and guard against harmful bacteria that enter the system. While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The digestive system ordinarily gets 20% to 25% of the oxygenated blood pumped out by the heart and the receptors in muscles provide the brain with information about body position and movement, the brain controls the contraction of skeletal muscle the nervous system regulates the speed at which food moves through the digestive tract.

Just a quick summary will do!:
A. Sickle Cell Anemia is caused by a base change in DNA. Describe how the base change results in a faulty protein being made.
B. Briefly explain the inheritance pattern of the condition.
Answer: a) The single base change mutation occurs at the beta chain of haemoglobin when glutamic acid is replaced with valine.
b) Sickle Cell Anemia is inherited in an autosomal recessive pattern.
Explanation:
Haemoglobin is a protein found in the red blood cells whose main function is to transport oxygen. Sickle Cell Anemia is a disorder caused by a base change in DNA beta chain of haemoglobin. The amino acid valine is substituted for glutamic acid at one point in each of the two beta chains. When this type of hemoglobin is exposed to low oxygen, it forms elongated crystals inside the red blood cells that are sometimes 15 micrometers in length. These make it almost impossible for the cell to pass through many small capillaries, and the spiked ends of the crystals are likely to rupture the cell membrane, leading to sickle cell anemia.
In describing the inheritance patterns of sickle cell anaemia, it is of autosomal recessive pattern. This means that the parent of the affected individual both carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. The gene for normal red blood cell is dominant over the gene for abnormal red blood cell which is said to be recessive. A person who is a stickler should have the genotype SS.
Part A - Processes that contribute to genetic variation Meiosis guarantees that in a sexual life cycle, offspring will inherit one complete set of chromosomes (and their associated genes and traits) from each parent. The transmission of traits from parents to offspring is called heredity. Another important aspect of meiosis and the sexual life cycle is the role these processes play in contributing to genetic variation. Although offspring often resemble their parents, they are genetically different from both of their parents and from one another. The degree of variation may be tremendous. Which processes lead to genetic variation in sexually reproducing organisms
Answer:
independent assortment, crossing over and random fertilization
Explanation:
There are three mechanisms by which sexual reproduction increases genetic variation in progeny. First, random fertilization is the process by which gametes randomly combine in order to increase the possibilities for genetic variation. Second, the independent assortment refers to the process by which pairs of homologous chromosomes independently separate from one another during meiosis. Finally, crossing over, also known as recombination, is the process by which two homologous chromosomes' non-sister chromatids can exchange genetic material during meiosis I (prophase I).

Answer: B. All are considered nonrenewable resources
D. All can be categorized as energy resources.
Explanation:
Non renewable resources are the resources that are in fixed quantity and can be used up. These include wood, petroleum, coal, steel, aluminum etc.
An energy resource simply refers to the resources that can be used to produce heat or electricity such as wood, petroleum, coal etc.
Coal, petroleum and wood are not renewable resources and they're not inexhaustible. They are exhaustible and non renewable resource.

1- carotenoid is a pigment that can be found in Chrysophytes
true
false
2- Diatoms are multicellular
true
false
Answer: 1. true
2. false
Explanation:
1. Chrysophytes can be defined as the algae that can be found in the lakes. They have photosynthetic pigments carotenoids which impart golden yellow color to these algae. They are unicellular and also have flagellum that help them in movement in water.
2. Diatoms are unicellular algae. They appear as single individual cells or may appear in colonies with other cells. They can take up any shape based on their alignment pattern. Each cell is surrounded by cell wall that is composed of silica called as frustule. They can be found in fresh or marine water.

what caused a decrease of carbon dioxide in the biodomes air
Answer:
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.
What are the factors responsible for decrease of carbon dioxide in the biodomes air?There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:
Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.
Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.
Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.
Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.
It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.
