Answer:
Space constraints.
Explanation:
Space constraints are the energetic constraints that prevent prokaryotes from getting larger than their limit. Space constraints control the sizes of both the largest and smallest bacteria. Bacteria can't shrink more than they have already because there is not enough space left for DNA and necessary proteins. In the same way, the prokaryotes can't increase in size beyond their limit due to space constraints.

The diagram below depicts the Linnaean classification system and a
cladogram. How do the two methods of classification compare?
A. Extinct organisms have a place in the Linnaean system, but not in
a cladogram
B. The Linnaean system attempts to show how organisms ans
related, but a cladogram does not.
C. The Linnaean system establishes a scientific naming system, but
a cladogram does not
D. The Linnaean system presents the probable order of evolution of a
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.

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

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..

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.
You have a microorganism you know is both fastidious and which normally lives in human lungs. Which medium might this organism have the highest probability of growing on and why
Answer:
It is likely that this microorganism grows in enriched culture media.
Explanation:
As shown in the question above, the microorganism that lives in the lungs is extremely demanding. This means that this microorganism is very difficult to be cultivated in a culture medium, as it requires specific nutrients and in specific amounts to be able to develop. These microorganisms are called fastidious microorganisms and need an enriched culture medium to develop.
Enriched culture media are those that have a high range of nutrients in their composition. These culture media are highly nutritious and for this reason, they are the ideal environment for demanding microorganisms, as it can efficiently meet the needs of this organism.

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.
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.

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
Describe the tissue stages of development. Include information on the embryonic germ layers and what they give rise to.
Answer:
Gastrulation takes place after cleavage and the formation of the blastula and the primitive streak. It is followed by organogenesis, when individual organs develop within the newly-formed germ layers. Each layer gives rise to specific tissues and organs in the developing embryo.Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to the gut and many internal organs.

What is a controlled variable?
Answer: A controlled variable or constant variable is a variable that does not change during an experiment.
Explanation:
A controlled variable or constant variable is one which the researcher holds constant (controls) during an experiment. It is also known as a constant variable or simply as a control.The control variable is not part of an experiment itself it is neither the independent nor dependent variable but it is important because it can have an effect on the results gotten.
example of a controlled variable is temperature.

A biologist is in the process of classifying a newly discovered fungus. a The fungus is a decomposer and has saclike
structures. The organism most likely belongs in the same group as which of the following?
O fungi that are rusts
fungi that are associated with bread mold
fungi that makes blue cheese
O fungi that are autotrophic decomposers
Answer:
fungi that makes blue cheese
Explanation:
Penicillium represents a genus of ascomycetous fungi that generate sexual spores referred to as axcospores, which form in sac-like structures named asci. Penicillium roqueforti is a filamentous fungus of this genus that is required for making blue cheese. This mold fungus (P. roqueforti) is a decomposer of organic materials that grows naturally in soils. P. roqueforti produces roquefortine C, a mycotoxin that is used as a starter culture for blue cheese production.
What is he process of gathering information, organizing it, and using it to adapt to the world
Answer:
Cognitive Experience
Explanation:
The process of gathering information, organizing it and using it to adapt to the world is cognitive experience. We collect data and information by understanding it and then try to simplify/interpret in a way that's more organized and easy to understand. When we put this knowledge to the real world by utilizing it, we're using our cognitive experience from the past and applying it to the current situation.
It's like a set of mental procedures which is the way the brain sees, learns, recalls, and thinks about all the details they notice with their five senses.

[tex]what \: is \: meaning\: of \: zindagi \:?[/tex]
were any of the features used in more then one phylum
Answer:
No.
Explanation:
No, the features is not used in more then one phylum because every phylum has its own unique characteristics which makes it unique from other phylum. Every phylum is different from one another due to its different features and characteristics so one feature that is present in one phylum is not present another phylum so we can say that any of the features were not used in more then one phylum.
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.
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.
