Hazards are identified in mission planning through a process known as risk assessment, comprising of identification of hazards, assessment of risk, development of controls and evaluation of control effectiveness, with continuous evaluation ensuring effective hazard management.

Hazards are identified during mission planning through a process known as hazard analysis or risk assessment. This involves reviewing all aspects of the mission, including its objectives, resources, and environmental conditions. It consists of four key stages: identification of hazards; assessment of risk; developing controls; and evaluation of control effectiveness.

For instance, if the mission is launching a satellite into space, potential hazards might include equipment failure, adverse weather conditions, or human error. Each of these risks is assessed in terms of its potential impact on the mission and the likelihood of its occurrence. Controls are then developed to help mitigate these risks, such as double-checking equipment, checking weather forecasts, and providing thorough training to all personnel involved.

Throughout this process, continuous evaluation is conducted to ensure that all identified hazards have been effectively managed, and the mission can be carried out safely and successfully.

The brainstem also includes other parts like the midbrain and the pons, which together support a range of automatic functions necessary for our survival.

Answer:

Plant cell parts are cell wall, chloroplast.  Animal cell parts are centrosomes and lysosomes.

Explanation:

Animal and plant cells are eukaryotic cells but still shows many structural differences.

Plant cells contain chloroplast because they perform the process of photosynthesis. Animal cells lack chloroplast. Cell wall is present in plant cells and absent in animal cells.

Animal cells have centrosomes that helps in the formation of spindle fibers,. Lysosomes perform the process of cellular digestion in animals.

        Mitosis divides a parent cell into two identical daughter cells, each of which has the same amount of chromosomes. Meiosis, on the other hand, creates four distinct daughter cells, each of which has half as many chromosomes as the parent cell.

Answer : A, B

      Daughter cells that are genetically identical to their parent cells are created during mitosis. The cell divides its copied chromosomes equally to ensure that each daughter cell has a full set before copying, or "replicating," its chromosomes.

      A single cell divides into two identical daughter cells during the process of mitosis (cell division). facts Describe meiosis. A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material.

     Despite being all haploid, the gametes created during meiosis are not all genetically identical.

        The nuclei produced from meiosis are not genetically identical and they carry one chromosomal set only. This is half the number of chromosome sets in the initial cell, which is diploid.

C,throwing a test tube at another student

Explanation:

Chlorophyll b is an accessory pigment. Chlorophyll a is an essential pigment.

The range of wavelengths that a pigment absorbs is known as its absorption spectrum. The absorption spectra of three important pigments involved in photosynthesis—chlorophyll a, chlorophyll b, and -carotene.

Chlorophylls come in five main categories: chlorophylls a, b, c, and d, as well as bacteriochlorophyll, a similar chemical found in prokaryotes. The two primary photosynthetic pigments in plants are chlorophyll a and chlorophyll b. Blue and red wavelengths are absorbed by chlorophyll molecules.

Therefore, Chlorophyll b is an accessory pigment. Chlorophyll a is an essential pigment.

Answer:

B. A secondary consumer that obtains its energy from the consumption of animals.

Explanation:

The red-tailed hawk is a secondary consumer because it feeds itself on primary consumers those that eat plants, herbivores. Secondary consumers, by definition, obtain their energy from eating other animals. Secondary consumers are also usually the ones that stand on the second and above rows of a food chain, being the plants at the bottom and the primary consumers just above the plants.

Answer: The correct answer is- d. competition.

Competition can be described as a biological interaction between individuals belonging to same ( intraspecific) or two or more different species ( interspecific) for territory, food, and other resources.

Dogs bark at unknown individuals, when they approach their house. By this behavior, they exhibit defense for their territory. This behavior is exhibited  because  dog is fearful and perceives strangers as a threat to their territory.  

Thus, option d) is the right answer.

Answer:

The correct answer is the sun.

The sun is the ultimate source of energy of a food chain. This energy is trapped by the green photosynthetic plants under the process of photosynthesis.

Plants only absorb 2-8% of the PAR (photosynthetically active radiation- 400 700 nm) fallen on earth.

In addition, only 10% of the energy is transferred from one trophic level to the next one and rest 90% is dissipated in metabolic process or heat.

It is the reason that earth receives 10,000 times the total energy used by human beings as we are present on I and II trophic levels in a food chain.

this is called LIQUEFACTION

The correct answer from these choices is liquefaction.

As cross-sectional area of a Muscle is proportional to __L2_____ and l is proportional to __M1/3_____, we have that strength is proportional to __M2/3.___.

Isometric scaling is the preservation of proportional relationships even as size of organisms changes through growth

Since it is assumed that all the organisms scale isometrically and also Given that L denotes the length and m denotes body mass of an individual the cross-sectional area of a muscle is proportional to L2 while I is proportional to M1/3 and the strength will be proportional to M2/3.

Hence we can conclude that As cross-sectional area of a Muscle is proportional to __L2_____ and l is proportional to __M1/3_____, we have that strength is proportional to __M2/3.___.

Final answer:

Vacuoles are membranous sacs present in eukaryotic cells and are involved in storage and transport. They are distinct from ribosomes, which are not membrane-bound and are involved in protein synthesis. Vacuoles are prominent in plant cells but are also found in animal cells, albeit smaller and less permanent.

Explanation:

Vacuoles are membranous sacs essential for the storage and transport of substances within eukaryotic cells. They are enclosed by a single membrane and vary in function from one cell type to another. In plant cells, vacuoles play several roles, including maintaining turgor pressure, storage of nutrients, and waste products, and can contain enzymes that break down macromolecules. In contrast to vesicles, vacuole membranes do not fuse with other cellular membranes. Although vacuoles are present in some animal cells, they are more prevalent and larger in plant cells, often consolidating into a single large central vacuole as the plant cell matures.

Ribosomes, another cellular component often mistaken with vacuoles, are the sites of protein synthesis. However, unlike vacuoles, ribosomes are not membrane-bound and are composed of ribosomal proteins and RNA. They can be found attached to the endoplasmic reticulum or floating freely within the cytoplasm. It's clear that vacuoles are not manufactured by ribosomes, nor are they composed of microtubules. They have specialized functions that are crucial for the cell's viability and operation.

The correct method of mineral formation for calcite and aragonite minerals that constitute clam shells is biogenic precipitation.

Biogenic precipitation is a process where minerals are formed as a result of biological activity. In the case of clam shells, the organism (clam) extracts calcium and carbonate ions from the surrounding water to form the minerals calcite and aragonite, which are both calcium carbonate (CaCO3) but have different crystal structures. These minerals are then deposited in an organized manner to create the hard, protective shell of the clam. This biological process is a key example of biomineralization, where living organisms produce minerals that often have specific functions, such as providing structure and protection.
