Answer:
isotonic solution
Explanation:
The cell membrane is semi-permeable, so it allows to pass through certain solutes. By a process called osmosis, the water molecules move from a compartment of lower concentration of solutes to a compartment with higher concentration.
Therefore, if the concentration of solutes in the outside is higher than the concentration in the cytoplasm (hypertonic solution), the water molecules will move from the interior to the exterior. Conversely, if the cytoplasm is more concentrated than the outside (hypotonic solution), the water molecules will move from the exterior to the interior. If the cytoplasm has the same solute concentration as the outside, the solution of the outside is called isotonic, and no water net flux will be produced.

that the flower serves in an angiosperm?
A. protects the seed in the ovary
B. collects pollen for fertilization
C. attracts pollinators
D. transfers seeds away from plant to grow

What is five kingdom classification?The main purpose of the classification of the Five kingdom has been known R.H. Whittaker. The five kindoms that has were included in this proposal were the Fungi, Protista, Monera.
Animalia as well as the kingdom Plantae. There are mainly five criteria or the conditions based on which the classification has been madeup of. These criteria has been includes the structure of the cell, as well as the nutrition mode, organisation of the thallus, or the relations of reproduction and phylogenetic.
Based on shoe characteristics they were to develop a classification hierarchy of shoes, beginning with the shoe "kingdom" and becoming more and more specific, just like scientists did for the classification of living things.
Therefore, The transfers seeds away from plant to grow is not a purpose that the flower serves in an angiosperm. Thus, option D is correct.

Explain Central Nervous System.
Explanation:
The central nervous system controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
Explanation:
central nervous system is made up of the brain and spinal cord. it receives and integrate impulses from the receptors and then relays them to effector organs. it is the centre of co ordination.

Speech is a dynamic process requiring precisely coordinated articulatory movements for the sequencing of sounds to ultimately produce words. What is common among children with cerebral palsy
Answer:
Speech impairment
Explanation:
Cerebral palsy children suffers speech impairment and it is the inability to produce speech sounds and this may range from mild to severe. This can include an articulation disorder, fluency disorder and voice disorder.
fluency disorder is characterized by inability to pronounce a sound or repitition of a particular sound.
voice disorder is characterized by the production of abnormal pitch or volume.
Articulation disorder in the inability to articulate words, it could include stammering.
Which is the best definition of directional selection?
a process by which two species can no longer reproduce
a process by which one of the extreme variations of a trait is favored
a process by which individuals with either extreme of a trait are favored
a process by which average individuals in a population are favored
Answer:
B. a process by which one of the extreme variations of a trait is favored
Explanation:
The graph for this type of selection looks sort of like a camel's hump. With that being said, the phenotype of a population experiencing directional selection goes from one extreme to the other. Reference the evolution of the peppered moth during the Industrial Age as an example.
Sincerely hope this helps! God bless!A process by which one of the extreme variations of a trait is favored best describes the directional selection. Therefore, option (B) is correct.
What do you mean by directional selection?Directional selection is a negative natural selection mode in which an extreme phenotype is preferred over other phenotypes, causing the allele frequency to shift over time in that phenotype's favor.
Fossil evidence suggests that while the size of European black bears decreased during interglacial periods of the ice ages, it increased during each glacial period. This is an example of directional selection. A further illustration is the size of a population of finches' beaks.
The behavioral trait in question experiences a concentration of increasing alleles in the line selected in the upward direction and a concentration of decreasing alleles in the line selected in the downward direction.

What do stabilizeing selection and disruptive selection have in common
Explanation:
Stabilizing selection is the opposite of disruptive selection. Instead of favoring individuals with extreme phenotypes, it favors the intermediate variants. Stabilizing selection tends to remove the more severe phenotypes, resulting in the reproductive success of the norm or average phenotypes.

Eukaryotic chromosomes contain two general domains that relate to the degree of chromatin condensation. These two regions are _
Answer:
This question lacks options, options are: A) Heterochromatin and euchromatin
B) Uniform in the genetic information they contain
C) Separated by large sketches of repetitive DNA
D) Each void of typical protein-coding sequences of DNA
E) Void of introns.
The correct answer is A.
Explanation:
The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.

A metric that measures the decline in population sizes, shrinkage of species, and geographic range is ________.
Answer: Living Planet Index
Explanation:
The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. It is used as a source of information to identify threats at the population level for each species on Planet Earth.
With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.
The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.

Write two sentences or clues, one for each word, that will help you remember the difference between actin and myosin. (Example: Actin is actively pulled)?
Answer:
The correct answer is -
Actin produces thin contractile filaments within muscle cells,
Myosin produces the dense contractile filaments within muscle cells
Explanation:
Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.
Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.
