Answer:

by analyzing how genes influence the development of phenotypic traits, i.e., by determining the association between phenotypic traits and changes in DNA sequence  

Explanation:

Genetics is a discipline that studies how genetic variation, i.e., the variation in the Deoxiriibunicleinc acid (DNA) molecule, is associated with the transmission of heredity, and how the environment influences this process. The DNA is a molecule that carries the instructions to perform all metabolic functions (eg., reproduction, development, growth, etc). Thus, advancements in genetics enabled us to decipher how phenotypic traits pass from parents/ancestors to their offspring/descendence. Genes are segments of DNA that carry the information (genetic information) to determine each phenotypic trait. During reproduction, genes are passed from one generation to the next, thereby transmitting this information across generations.

Answer:

to adapt to dryland conditions

Explanation:

The main groups of land plants are vascular plants and they have developed diverse adaptations to survive on land, especially in climatic zones where drought and high temperatures are common. Some of the most important plant adaptations to land ecosystems include, among others, the development of a cuticle to prevent water loss, stomata capable of regulating water evaporation, desiccation-resistant spores coated in sporopollenium polymer, etc. Moreover, in seed plants, which are considered to be the most evolved vascular plants, the endosperm tissue produced inside the seeds is nourished by the parent sporophyte during the first stages of plant development.

Desiccation resistant spores, protective and complex

tissues enable land plants to adapt to dry conditions.

Answer:

The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.

3.You might think this should mean you need to cut out salt completely, but salt is actually an important nutrient for the human body. Your body uses salt to balance fluids in the blood and maintain healthy blood pressure, and it is also essential for nerve and muscle function.

4.Cooling the mixture is to prevent the DNA from being degraded by the heating.

5.The ethanol pulls water from the DNA molecule so that it then collapses in on itself and precipitates. The DNA will become visible as white mucous strands that can be spooled with the wooden applicator stick.

6.The colder the ethanol is the greater the amount of DNA that is precipitated. (You could try having some of the students use room temperature ethanol and see if the amount of DNA they can spool is the same or less than that for the groups using the ice-cold ethanol.

The only body structure that has walls one cell thick is capillaries.

Capillaries, the blood vessels in our bodies are so minuscule that red blood cells can only travel through them in a line. Comprised of a layer of cells capillaries facilitate the exchange of crucial substances like oxygen carbon dioxide, nutrients and waste materials, between the bloodstream and the surrounding tissues.

With the above details we can conclude that the  body structure that has walls one cell thick is capillaries.

Answer:

food, water, habitat

Explanation:

Answer:

Frogs need suitable land and freshwater habitats in order to survive. They also have highly permeable skin that can easily absorb bacteria, chemicals and other toxins.

Fats that increases the bad cholesterol in the body are considered worst. Thus, Trans unsaturated fat is the correct answer.

Unsaturated fatty acids have the presence of double bonds. This double bond is either 'cis' or 'trans' in origin.

When the unsaturated compounds are linked through trans bond, they form trans fat.

Trans fat are produced through chemical reaction. This reaction is termed as partial hydrogenation.

Trans fats have shown potential damage to the human body in research studies. Trans fat raises the bad cholesterol level (more lipid, less protein) in the body.

This can lead to several heart disease, liver damage or even atherosclerosis. Such diseases can be life threatening.

Trans fat are found mainly in fried and processed food. The junk food also contains high levels of trans fat.

Therefore, consumption of trans fat should be avoided for health safety.

Explanation:

It's part of RNA

Answer:

B

Explanation:

When DNA goes to RNA, you have to find the matching pair. G goes to C, A to U, T to A, and C to G. Ask for any clarification!

Answer:

C. This process is translation and involves the production of proteins from RNA.

Explanation:

- In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids.

Translation

Answer:

True

Explanation:

This statement is true. A species can always change over time and adapt to their environment.

A species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. It is a class of plants or animals whose members have the same main characteristics and are able to breed with each other.

Moreover, it is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behavior or ecological niche.

Hence, species can change over time and adapt the conditions according to their environment.

Explanation:

Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth's mantle. Seafloor spreading creates new crust.

Answer:

Measurement (Count) of Cell Numbers:

1. Breed Method:

A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.

Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.

Answer:

cell mass: The total mass of all the cellular elements in the body which constitute all the metabolically active tissue of the body

Cell number: The sequence of numbers or characters, that when dialed, connects to a particular cellular telephone

Answer:

One Joule.

Explanation:

One newton exerted over a distance of one meter equal to one joule.

Joules is the S.I unit used for the measurement of scientific quantities such as work and energy and it was named after the prominent English physicist, James Prescott Joule.

Given the following data;

Force = 1N

Distance = 1N

Therefore, we know these parameters or quantities are directly related to work.

Mathematically, work done is given by the formula;

Work done = force * distance

[tex] W = F * d[/tex]

Where,

Substituting into the equation, we have;

[tex] W = 1 * 1[/tex]

Work done = 1 Joule.
