Answer:

Evolution works independently of natural selection

Organisms best suited for environment survive and reproduce statement accurately describes natural selection

Explanation:

Natural Selection: Organism adapts itself to the particular environment to survive and reproduce.

The theory of Natural selection was popularized by Charles Darwin. He explained that organisms evolved, they can survive when they get adapted better to the environment.

Natural selection is also called the'' survival of the fittest''. The organism which gets adapted to the environment will survive.

The more desirable characteristic will pass from parents to offspring.

The reason why interdisciplinary science is important to society is because of the following reasons; It has incorporate sources of knowledge and it is a way of increasing our knowledge. This science has made people realize and learn more things than they actually know and it made people understand things around them without having to actually think an explanation behind it.

Answer:

The diversity index is defined as the measure of diversity that describes the number of species that is present and also the relative abundance of individual species.

The invasive species are those species that are dominant in character and their presence can cause a negative impact on the ecosystem. They have the ability to create dis-balance in an ecosystem. For example, Asian Carp, European Starling, and Water hyacinth.

An increase in the number of invasive species leads to a decrease in the diversity index. This species can alter the food web within an ecosystem by eliminating the local food sources leaving no food for the faunas.

Thus, these species must be kept under control in order to maintain a favorable condition for the other species to exist in an ecosystem.

There are several septum's within the body. The term septum simply just means, a divide between two things. If you are referring to the cardiac septum; which separate the heart into left and right sides. There is a top portion of the septum which is called the atrial septum and the bottom portion of the septum; which is called the ventricular septum. They typically keep the deoxygenated blood and the oxygenated blood separated from each other.

If you're referring to the nasal septum, the nasal septum acts as a pathway stabilizer to make sure that the air we breathe in is not "lost" and gets resistance going into our lungs.

The septum in the heart, including the interatrial and interventricular septa, separates the chambers to ensure efficient circulation. The nasal septum, comprising bone and cartilage, divides the nasal cavity into two parts and supports nasal structure and function.

The septum is a central structure in the anatomy of the heart that serves as a divider between its chambers, ensuring proper circulation of blood throughout the body. Two primary types of septa exist within the heart: the interatrial septum and the interventricular septum. The interatrial septum separates the left and right atria and features the fossa ovalis, which is the remnant of the foramen ovale from fetal development. This foramen ovale provided a pathway for blood to bypass the lungs and flow directly from the right atrium to the left atrium before birth. Shortly after birth, it is sealed by the septum primum. The interventricular septum, which is thicker than the interatrial septum, separates the left and right ventricles and is fundamental in maintaining the division between the high-pressure systemic and lower-pressure pulmonary circulatory circuits.

Aside from the heart, the nasal septum is another significant septal structure in human anatomy. It is a flat, midline structure that divides the nasal cavity into two halves, comprising the perpendicular plate of the ethmoid bone, vomer bone, and septal cartilage. This partition plays a critical role in directing airflow and supporting the structure of the nose.

Increased genetic variation  is an advantage of reproduction. thus option B is correct.

There must be some evolutionary means by which existing DNA sequences are changed and new sequences are incorporated into the gene pools of species is called genetic variation.

It increases chances of survival in the living organisms as some of the variations are acquired genetically due to change in segregation of chromosome during reproduction or due to adaptations these changes will increase the chances of survival of the organism is unfavorable conditions.

Answer: D. receive oxygen

Explanation: Breathing is a coordinated effort of various respiratory system organs to receive oxygen and eliminate carbon dioxide. The cardiovascular system works in coordination with the respiratory system to receive oxygen into the blood and remove carbon dioxide out of the blood... PF

Breathing is a coordinated effort of respiratory organs to receive oxygen.

Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product.

The breathing of all vertebrates with lungs consists of repetitive cycles of inhalation and exhalation through a highly branched system of tubes or airways which lead from the nose to the alveoli.

Therefore, Breathing is a coordinated effort of respiratory organs to receive oxygen.

These macromolecules might either be amino acids, proteins or nucleic acids. They are accountable for the chemical changes and reactions that moves largely the cell and its composition. Take for example the cytoplasm of the cell where these organelles are settled. These simple organelles are composed of macromolecules which ignites and catalysis different functions that enables cells, in macro-perspective in motion and metabolism. In intestines for instance, metabolism occurs and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components. 

The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.

The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.

The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.

The answer to your question is:

They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.

Enzyme activity is highly dependent on temperature and pH. Optimal temperature for human enzymes is usually around 37 degrees Celsius, and deviations can lead to decreased activity or denaturation. Similarly, each enzyme has an optimal pH range, with performance dropping off outside this range due to structure-altering changes in H+ concentration.

The activity of enzymes is greatly influenced by changes in temperature and pH. At their optimal temperature, usually around 37°C for human enzymes, they perform at their peak. Deviation from this temperature can lead to a decrease in activity. High temperatures may cause denaturation, changing the enzyme's structure and preventing substrate binding. Conversely, low temperatures reduce kinetic energy, slowing down reactions.

pH also plays a crucial role in enzyme function. Each enzyme has an optimal pH range where it performs best. For example, enzymes in the stomach, like pepsin, work effectively at a low pH due to the acidic environment. On the flip side, enzymes like trypsin operate in the basic environment of the small intestine. Should an enzyme's environment fall outside its pH range, the change in H+ concentration can alter the enzyme's structure and reduce its activity or even result in denaturation.

Understanding these conditions is critical because enzymes rely on their 3-dimensional shape to function. The noncovalent interactions, such as ionic bonds and hydrogen bonds, that maintain their shape are sensitive to changes in temperature and pH, which can disrupt these forces and the enzyme's activity.

Answer:

The correct answer will be- fatty acid chains and glycerol molecule.

Explanation:

Lipids are the biomolecules also known as triglycerides.  The lipids get hydrolyzed to provide energy to the body through the process of lipolysis which takes place in the cytoplasm.  

The triglycerides on breakdown form the two components, fatty acids and glycerol in which fatty acid undergo β-oxidation and gets converted to acetyl CoA whereas the glycerol directly enters in the glycolysis pathway as DHAP. The lipolysis provides high energy to the body.

Thus, fatty acid chains and glycerol molecule is the correct answer.

A habitat is the place where a plant or animal lives. All living things have adaptations that help them survive in their habitats. For example, plants and animals can only live in habitats that meet their needs.

An ecosystem is a group of animals and plants and their physical environment. Coral reefs are underwater ecosystems. Coral reefs are made from skeletons of tiny creatures. Deserts are also ecosystems and they get dry weather and very little rain.
