The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.
Explanation:
In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.

Answer:
Prokaryotes
Explanation:
The basic functions which are important for the survival of an organism include processes such as homeostasis, nutrient absorption and distribution in body, reproduction, and defense against injury or pathogens.
There are usually nine organ systems present in an animal which includes skeletal, muscular, nervous, endocrine (hormonal), digestive, respiratory, circulatory, excretory (urinary), and reproductive system. Each of these systems perform a specific function.
The Skeletal system provides the body structure and is responsible for the movements of different body parts. The muscular system is made up of all the muscles which are present in the body, these help in connecting different body parts to the skeletal system. The nervous system consist of the brain and the spinal cord, this system is responsible for coordinating different functions in the body.
The endocrine system is responsible for secreting hormones which are responsible for the growth and development of body. The digestive system helps in absorbing the energy present in the food and distributing the energy. The circulatory system is responsible for the circulation of gases and different molecules across the body through blood vessels.

Answer:
The heart pumps blood through the circulatory system, delivering needed materials (glucose, oxygen) and picking up waste (carbon dioxide) from cells all over the body. Organs systems work together to efficiently and effectively provide all body cells with their basic needs to carry out life functions.
b. myofilament
c. sarcolemma
d. endomysium
Answer:
Sarcomere
Explanation:
Myofibril is the unit of the muscle cell. The myofibril is rod like in structure and developed by the process of myogenesis in embryo.
Sarcomere is the basic structural unit of the skeletal muscles and shows striations under the microscope. Sarcomere consists of thick and thin filaments of actin and myosin. Different bands like A- band , H-Band, I-Band and Z- line is visible in the sarcomere.
Thus, the correct answer is option (A).
Answer:
Natural Selection.
Explanation:
I remember this in bio.
Answer:
The Answer is Natural selection
Explanation:
The best definition for a macromolecules is the most abundant elements found in living cells. The correct option is d.
A macromolecule, such as a protein or nucleicacid, is a very large molecule that is important in biophysical processes.
It is made up of thousands of atoms that are covalentlybonded. Many macromolecules are polymers composed of smaller molecules known as monomers.
Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.
Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.
Macromolecules are made up of monomers, which are single units joined together by covalent bonds to form larger polymers. The most abundant elements found in living cells are the best definition for macromolecules.
Thus, the correct option is d.

Your question seems incomplete, the missing options are:
a. a trace element
b. a vitamin
c. an organic molecule necessary for life
d. the most abundant elements found in living cells
Answer:
There are no answers to choose from.
Explanation:
However, the prefix macro- means big, so the word macromolecule means large molecule. Macromolecules are also known as the molecules of life, they all contain carbon. The four macromolecules are carbohydrates, proteins, lipids, and nucleic acid. Carbohydrates are used as a quick energy source, they can be broken up into monosaccharides, dsaccharides, and polysaccharides. Proteins are used as catalyst to help speed up chemical reactions. Lipids are also known as fats, they can either be saturated or unsaturated. Nucleic acids contain information.
Examples of each:
Carbohydrate- Gluten
Protein- Lactase
Lipid- butter, or oil
Nucleic Acid- DNA or RNA
Answer:
there are three different species.
Explanation:
There are three different species of monkey according to the hypothesis because all monkey species have different feeds i. e. one feed on the fruits while the other feed on the tree sap. It also shows that two monkey species have same feed i. e. eating fruits while one specie feeds on tree sap. This hypothesis also shows that no specie of monkey feeds on leaves and insects present on the trees.
