Answer:
formation of gametes.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
Differentiation can be defined as the process in which a cell changes from a generalized cell type into a specialized cell type for performing specific functions in the body.
Mitosis can be defined as a type of cell division that occurs in all body cells found in living organisms.
Hence, all of the aforementioned statements refer to mitosis, except formation of gametes.
In living organisms, the formation of gametes is linked or has to do with meiosis.
Chromosomal sex refers to the physical expression of male or female anatomical structures based on the presence or absence of specific hormones that are secreted after the seventh week of prenatal development.
Question 11 options:
True
False
Answer:
I think its true
Explanation:
The chromosomal sex of the embryo is established at fertilization. However, 6 weeks elapse in humans before the first signs of sex differentiation are noticed. Sex differentiation involves a series of events whereby the sexually indifferent gonads and genitalia progressively acquire male or female characteristics.

What does it mean that a hypothesis must be ‘falsifiable’ in order to be valid?
\
Answer:
A hypothesis must be able to be proved wrong for it to be a useable hypothesis.
Explanation:
This is because if one can not disprove a hypothesis no experiment can be preformed to test the truthfulness of the statement. this does not mean that the question is not interesting or not worth asking. For example "There is a god" is an example of a hypothesis which is not falsifiable; whether or not this statement is true is still valuable information but it is not possible to answer using the tools of science.
Answer:
If an experimental observation can be made that disproves a hypothesis or model, it is said to be falsifiable. That is, one of the possible outcomes of the planned experiment must be a result that would contradict the hypothesis if achieved..

When flies having a gray body and normal wings were crossed with flies having a black body and vestigial wings, the F2 generation showed a phenotypic ratio of 3:1, and not 9:3:3:1.
Answer:
This proves Gregor Medel's hypothesis.
Explanation:
When Gregor Mendel crossed two pure-breed flowers, he noticed that the offspring in the F1 generation exhibited all dominant traits. However, when he crossed the offspring in the F1 generation, he noticed that the recessive trait reappeared in a 3:1 ratio (one reccesive). This is because for each trait, one allele from each parent is passed on. Also, the alleles are passed independently of one another, meaning that one allele passed for one trait won't affect the chance of another.

set of organisms, but a cladogram does not
Answer:
C. The Linnaean system establishes a scientific naming system, but a cladogram does not.
Explanation:
The main difference between Linnaean classification system and a cladogram is that the Linnaean system establishes a scientific naming system, but a cladogram does not. Cladogram refers to a branching diagram which shows the cladistic relationship between different species while on the other hand, the Linnaean system of classification consists of taxa that is range from the kingdom to the species.

When conducting a chemotaxis assay to test if the experimental RNAi treatment affected C. elegans, what is the purpose of using sodium azide on the chemotaxis assay plates
Answer:
It is a metabolic inhibitors.
Explanation:
The purpose of using sodium azide on the chemotaxis assay plates causes stress protein expression and creates the ability to tolerate high temperature. Sodium azide inhibits oxidative phosphorylation through inhibition of cytochrome oxidase that result in a rapid depletion of ATP. Exposure to the metabolic inhibitor i.e. sodium azide causes stress protein expression and tolerance to high temperatures in the nematode Caenorhabditis elegans.
A therapist examining the roles, rules, expectations, power hierarchy, and boundaries within a
family is focused on which of the following areas of assessment?
Answer:
This question lacks options, options are:
A) family affect
B) family strengths
C) family process
D) family organization.
The correct answer is D.
Explanation:
The family is a system that is constituted by a network of relationships and made up of subsystems where each member evolves and develops through different stages, undergoing adaptation changes where the norms, rules, limits and hierarchies that work are essential in the family environment. Family therapy is understood to be that modality of therapy focused on the family as an object of intervention, its objective is to achieve the change of negative interaction patterns between the members of a family. Family organization refers to the interaction between all its members who are part of the same institution united by emotional ties. The organization describes the totality of the existing relationships between the people that make up the system, then the family organization refers to the functional demands, distribution of rules and transactional guidelines that constitute the ways of interacting of each individual within the family. The transactional guidelines are those that normalize the behavior of each member and are preserved by two systems of coercion; the first established by universal norms in turn existing roles and hierarchies; the second is the characteristic of each member involving its interests and expectations.
Rachel is studying the impact of watching television 30 minutes before bedtime on quality of sleep. Which of the following might be the best hypothesis for her study?
Answer:
''Watching television adversely impacted the quality of sleep''.
Explanation:
''Watching television adversely impacted the quality of sleep'' is the best hypothesis for her study. Watching television right before bed, can negatively impact your sleep quality. Late-night watching television disrupts your internal clock that adversely affected sleep quality of an individual. The above hypothesis is used by the Rachel to investigate the impact of watching television before sleeping on the sleep quality.
Which of the following lists correctly presents levels of organization from most complex to simplest?
O biosphere, community, organism, organ system
O cell, organelle, atom, molecule
O macromolecule, population, community, ecosystem
Answer:
O macromolecule, population, community, ecosystem
Explanation:
Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).
The correct option is macromolecule, population, community, ecosystem

If you wanted to study large, migratory grazing animals like wildebeest, which biome would you chose to visit?
Answer: Savanna
Explanation:
The Savanna is a biome located in Africa and characterized by a lot of grass and dispersed trees. The climatic conditions are warm all year round and the summers are wet.
The presence of so much vegetation makes it an ideal biome for large herbivores like elephants, giraffes and wildebeests. As a result of so many herbivores being there, there are lots of carnivores as well such as lions and cheetahs.
╭☞ If you wanted to study large, migratory grazing animals like wildebeest, which biome would you chose to visit?
ANSWER:╭☞ Savanna or Savannah
Explanation:
╭☞ Because Savanna or savannah, is a migratory grazing animals like wildebeest and type of plant that grows under hot, seasonal climatic conditions and is characterized by an open tree trunk (i.e., scattered trees) above a continuous- continuous tall grass understory (the layer of vegetation between the canopy of the forest and the ground).

The fundamental source of Energy for all biological System is
Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

hi,I was feeling so bored so I give this question What is climate change and what r the causes of climate change?
Answer:
Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet (regarding temperature, precipitation, and wind) that are especially caused by human activities
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry
Deforestation – because living trees absorb and store carbon dioxide
Increasingly intensive agriculture – which emits greenhouse gases like methane and nitrous oxide
