Answer:

Both plant and animal cells

Explanation:

Answer:both plant cells and animal cells

Explanation:generally, cells obtain energy from food during cellular respiration where glycolysis takes place

Answer:

Phrases that are used only in one area of the country

Explanation:

Correct on the test :)

Answer:

the organelle that regulates cell function and contains the DNA is a nucleus

Answer:

blastopore

Explanation:

Involution is the second stage after invagination during frog gastrulation. Involution occurs at the blastopore when the marginal zone cells get to the tip of the blastopore, make an inward turn and then move along the inner exterior of the outer cells sheets.

This means that the cells found at the lip of the blastopore and always undergoing change and the first of these cells to develop into the dorsal lip are the endodermal cells. Next are the mesoderm cells that form the Notochord.

Answer:

True

Explanation:

Hyperglycemia which means high Glucose level in the blood as a result of lack of insulin can damage the glomeruli. This interfere with the function of the glomeruli. Normally glomeruli fiters blood and remove nutrients to form urine but hyperglycemia will affect it's negatively and will make protein to leak from the blood into the urine. This can also lead to glomeruli called glomerulosclerosis.

Answer:

animals also have to cope i the desert, using adaptations such as being nocturnal or living under ground to survive. camels often live in deserts that are hot and dry during the day, coping with wind-blown sand and cold at night. slit-like nostrils and two rowa of eyelashes to help keep the sand out of their eyes.

Explanation:

These modifications include phosphorylation, glycosylation, ubiquitination, nitrosylation, methylation, acetylation, lipidation and proteolysis and influence almost all aspects of normal cell biology and pathogenesis.

Answer:

B)CARBON DATING

Explanation:

Answer:

Lipase is an enzyme that helps in the catalysis of the hydrolysis of fats and other carboxylic acid esters. Lipases act/functions according to the substrate molecule constituent and how similar the chemical linkages are.

Lipase action on fats and carboxylic esters which are different molecules but with similar chemical constituents and bonds explains enzyme action only some unique bonds in a compound.

Answer:

These organisms evolved inside these countries.

Explanation:

Organisms evolved inside Australia and New Zealand countries because these two countries are isolated means there is no way for the movement of crops or animals from other regions into these environment. There is a big ocean present between these countries and other countries so the organisms only evolved inside these two countries not from the outside environment.

Answer:

The correct answer is - It shows that an RNA probe is necessary to get a signal.

Explanation:

A probe is a specific single-stranded sequence of DNA or RNA that recognizes its complementary sequence in a particular sample genome for synthesis. The RNA probe is placed into close contact with the given sample under a specific environment that allows the RNA probe sequence to hybridize with its complementary sequence.

In this case, square a is the condition where no RNA probe is persent whereas all three other conditions have some sort of RNA probe, however, in C there is no Gene X probe but their probe present. To get a signal in hybridization RNA probe is required and that can be used as control as it can be used to compare if a signal is received or not.

Answer:

B. Every human has a unique set of cultural traits and practices.

Explanation:

Culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

This ultimately implies that, culture are acquired and passed from one generation to another.

A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication.

This ultimately implies that, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.

Hence, the statement which is true of human cultures is that every human (race) has a unique set of cultural traits and practices that were acquired from the environment and society.

Answer:

Answer:

A. nucleus

Explanation:

The nucleus is particularly among the eukaryotic organelles because it is the location of the cell DNA two other critical organelles are mithochondrua and chloroplast ,which play important role in energy conversation and are through to their evolutionary origin as simple single called organism

Answer:

a sound wave moves through air by displacing air particles in a chain reaction, sound energy is associated with vibrations created by a vibrating source, that requires a medium to travel, which makes sound energy a mechanical wave

Explanation:

hoPE that helped :)

Answer:

Mechanical waves move "things"...they require a medium (whose molecules are the "things") to transmit their energy. Sound uses air molecules most of the time. It can use water molecules as well.

Answer:

nnnoooo

Explanation:

Answer:

Nature selects best suited organisms having behaviours that help in the survival of organisms in that environment.

Explanation:

Natural selection can shaped the behaviors that are learned by the organisms because these behaviours helped organisms in their survival. Those organisms will be selected by the nature which can withstand the changing environmental conditions. Organisms adopt different behaviours in order to survive harsh environmental condition and these behaviour shaped by the natural selection in that organism so that they survive and grow in that environment.

Answer: They adapt and become resistant

Explanation:

Just as many organisms adapt to survive the main goal of a virus is to also survive by mutating it’s becoming resistant to previous medicine

Hope this helps

Answer:

Explanation:

The missing diagram in the question is attached in the image below.

(A)

From the image below, the frequency of occurrence is shown in the last column.

The frequency of occurrence means the particular band for the entire whole population.

As an example:

1 in 15 frequency of occurrence means; ⇒ One (1) out of every fifteen (15) people has the band.

1 in 450 frequency of occurrence means; ⇒ One (1) out of every 450 people has the band.

(B)

However, Let the probability that Joe and Sam are twins be = A

and the probability that they are not twins be denoted with B;

Then;

P(B) = 1 - P(A)

where;

P(A) = Probability of specific bands appearing on the gel in every one of them

[tex]P(A) =\Big( \dfrac{1}{15}\times \dfrac{1}{15}\Big)\times \Big( \dfrac{1}{450}\times \dfrac{1}{450}\Big)\times \Big( \dfrac{1}{32}\times \dfrac{1}{32}\Big)\times \Big( \dfrac{1}{70}\times \dfrac{1}{70}\Big)[/tex]

[tex]P(A) =\Big( \dfrac{1}{225}\Big)\times \Big( \dfrac{1}{202500}\Big)\times \Big( \dfrac{1}{1024}\Big)\times \Big( \dfrac{1}{4900}\Big)[/tex]

P(A) = 4.37 × 10⁻¹⁵

∴

P(B) = 1 - P(A)

P(B) = 1 - 4.37 × 10⁻¹⁵

P(B) ≅ 1

Answer:

Thickness and number of chlorophyll.

Explanation:

Shade-adapted plants differ from sun-adapted plants due to many characteristics such as thickness and number of chlorophyll. Sun leaves are more in thickness than shade leaves because they develop longer palisade cells. Shade leaves generally have more chlorophyll as compared to sun-adapted plants. Specific leaf area and root mass fraction of Shade-adapted plants are higher as compared sun-adapted plants due to large number of chlorophyll to harvest more sunlight for photosynthesis. Dark respiration is higher in sun-adapted plants when there is darkness as compared to shade-adapted plants which produce food in no direct sunlight.

Answer:

Phagocytic defense in the normal lung is shared principally by two kinds of cells - alveolar macrophages that reside on the air surface and roam the alveoli and PMNs that circulate in the intravascular space or are stored transiently in areas adjacent to the capillary-alveolar interface (marginated in capillaries)
