Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M
in an appropriate design experiment, a scientist is able to test the effect of?
Answer:
This question is incomplete as it lacks options, the options are:
A) a single variable
B) multiple variables
C) the hypothesis
D) scientific observations
The answer is A
Explanation:
An experiment is conducted to solve a particular problem or find answers to a given scientific question. In an experiment, which usually consists of variables, only A SINGLE VARIABLE is tested at once.
This means that the effect of a variable called INDEPENDENT VARIABLE is tested at a time. The independent variable is the variable that is changed or manipulated in an experiment. This means that only a SINGLE VARIABLE can be changed at at time in an an appropriate design experiment.

Answer: Energy is released when bonds in the food molecules are broken during digestion.
Explanation:
In other words, how are we speeding up the effects of the competitive exclusion principle and thereby altering the outcome of that ecosystem's natural succession
Answer: Overgrazing, overfishing, and forest fires
Explanation:
Competitive exclusion principle two species which have the same ecological niche cannot exists together as such species will be competing for the same resources. The species which is superior over the other will receive the resources and the other species having no competitive advantage will not survive in future.
According to the given situation, human being is the most superior species on earth and have competitive advantage of thinking ability and intelligence over other species. Succession are the changes that occur in the biotic community of an ecosystem with respect to time.
The human beings can speed up the effects of the competitive exclusion principle by various ways: Overgrazing, overfishing, and forest fires. The overgrazing of the cattle in the field can remove the vegetation cover of the region and the land will become barren so instead of progressive succession in terms of vegetation cover the succession will again re-initiate in terms of primary succession if environment supports.
Overfishing can cause the exclusion of some valuable species of fish and there will not be evolution of such species and will alter the outcome of natural succession.
Forest fires can affect both floral and faunal species some species may tolerate the fire and will survive and some precursors like roots of the plants can support new individual plants. This will again alter the outcome of natural progressive succession in an ecosystem.
Which statement is true regarding the transmission of sex-linked traits in a population?
O Males cannot carry recessive alleles for sex-linked traits.
O Males cannot express dominant alleles on the X chromosome.
O Males cannot express recessive alleles on the X chromosome.
O Males cannot pass alleles for sex-linked traits to their daughters.
Answer: none of the statements are true
Explanation: Males can have a recessive copy of a X-linked gene, and can pass that on in the X containing gamete and so pass it on to daughters, but not to male offspring. Males will express whichever allele, dominant or recessive that they carry.
What step occurs in the cristae?
The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.
What is mitochondria?Mitochondria are cell organelles that generate the maximum of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.
Thus, the process name is oxidative phosphorylation.

What are the two main types of cells and where are they found in the human body?
Answer:
They are prokaryotes and eukaryotes and prokaryotes are single celled and eukaryotes are multi celled
Explanation:
Hope that helps! Have a fantastic day!
The two types of cells found in the human body are blood cells and immune cells.
What are cells?Cells are the fundamental foundations of all life. Trillions of cells make up the human body.
They support the body's structure, absorb nutrients from food, repurpose those nutrients into energy, and perform specialized functions.
Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic compounds found in all cells.
A cell is made up of three parts: the cell membrane, the nucleus, and the cytoplasm that lies between the two.
The cytoplasm contains complicated accommodations of fine fibers as well as hundreds or even thousands of tiny but distinct structures known as organelles.
Thus, there can be many cells in a human body, the most important perhaps are blood cells and immune cells.

In cucumbers, dull fruit (D) is dominant to glossy fruit (d), and orange fruit (R) is dominant to cream-colored fruit (r). The gene that codes for dull versus glossy assorts independently from the gene that codes for orange versus cream-colored. A plant that has dull and orange fruits is crossed to a plant that has dull and cream-colored fruits. The cross produces eight total progeny, with three plants that have dull and orange fruits, three plants with dull and cream-colored fruits, one plant with glossy and orange fruits, and one plant with glossy and cream-colored fruits.
Determine progeny phenotypic ratios - texture. To determine the actual genotype of the parents from among the possible genotypes identified in the previous step, separate the cross into two single-locus crosses, looking at the inheritance of each trait by itself. Start with the texture characteristic.
What is the fraction that represents the number of dull progeny?

(B) an increase in osmotic pressure of blood
(C) drinking water
(D) abnormally low blood pressure
A) Identify a human disorder with developmental limitations that results from changes in chromosome number. Explain how nondisjunction leads to changes in chromosome number.
B) Mutations result in changes to genotype that can result in changes in phenotype. Explain how a mutation causes a change in the genotype of an organism AND may result in a change in the phenotype of an organism.
Answer:A) Patau Syndrome (Trisomy 13) causes intellectual and physical disability, such as underdeveloped eyes, extra fingers/toes, heart defects. Survival beyond the first year is uncommon.
B)
Explanation: Trisomy (or aneuploidy in general) can result when chromosomes to do not separate correctly during mitosis or meiosis. In meiosis, non-separation of a chromosome pair results in a gamete with two copies of the chromosome (and consequently one gamete lacking the chromosome.
At fertilisation the embryonic cell will have three copies of the chromosome (and an embryonic cell with one copy only). These are serious mutations, many of which are non-viable and usually abort spontaneously. Others results in abnormal development and poor survival rates. Only one autosomal trisomy (21) and sex chromosome trisomies (XXX, XXY etc) result in babies that survive into adulthood, albeit with physical and developmental abnormalities (trisomy 21 abd trisomy X). Only one monosomy (XO) is viable.
Other mutations can be less inimical, and may not result in any variation from normal. Mutations in genes coding for proteins or ribosomes may result in potential loss of function. As there are two copies of each gene, the mutated gene is paired with a normal gene and if that is expressed there will be no loss of function.
There are cases where the mutated gene is dominant it will change the phenotype. An example is Marfan Syndrome, an autosomal (chromosome 15) dominant mutation resulting in connective tissue abnormalities and long bones.
An autosomal recessive mutation is not expressed but is carried. If both parents are carriers, the probability of offspring to be doubly recessive and have an altered phenotype is 25%. Cystic fibrosis is an example.
A third possibility is where two alleles are co-dominant. An example of this is sickle cell disease. Consider the three allele pairs SS, Ss and ss.
Those with ss have sickle cell anaemia, a painful and debilitating condition. Those with SS have normal blood cells. Those with Ss have sickle cell trait, which has some mild deficits because a proportion of blood cells are abnormal.

4. Take a beaker (jar or jug) with some water and put some drops of red or blue
ink in it. Take a tender twig of any flowery plant with leaves and flowers, preferably
white flowers, and put it in the beaker for 6 to 8 hours. What do you observe? For
further examination cut across its stem and look for the presence of colored water.
Explain your observations.
Answer:
Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.
The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.
Explanation:
The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.
The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.
When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.
