Answer:
The phosphate groups allow the nucleotides to link together, creating the sugar-phosphate backbone of the nucleic acid while the nitrogenous bases provide the letters of the genetic alphabet. These components of nucleic acids are constructed from five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorous.

How long will it take for 40.0 grams of Radium-226 (Ra-226) to decay to leave a total of 2.5 grams of Ra-226? Ra-226 has a half-life of 1600 years.
Answer:
6400 years
Explanation:
Given that;
N/No =(1/2)^t/t1/2
No = amount of radioactive material originally present
N = amount of radioactive material present at time t
t= time taken for N amount of radioactive material to remain
t1/2 = have life of the radioactive material
2.5/40 = (1/2)^t/1600
1/16 = (1/2)^t/1600
(1/2)^4 = (1/2)^t/1600
4 = t/1600
t = 4 * 1600
t = 6400 years

The processes of diffusion and active transport are both used to * break down molecules to release energy move molecules into or out of cells of the body bring molecules into cells when they are more concentrated outside of the cell move molecules against a concentration gradient, using ATP molecules
Answer:
move molecules into or out of cells of the body
Explanation:
Majorly, there are two types of transport used by living cells. These are; passive and active transport. Passive transport involves the movement of molecules down a concentration gradient without the need for energy (ATP) input. Example is DIFFUSION AND OSMOSIS.
On the other hand, active transport is a type of transport that moves molecules against a concentration gradient (low to high) with the aid of energy input (ATP). Example is sodium-pottasium proton pump.
Although there are obvious differences between these two processes (diffusion and active transport), but they both MOVE MOLECULES INTO OR OUT OF CELLS OF THE BODY.

A population of wolves migrate North in search of food. As the wolves travel they enter a region that has long, snowy Winters. This makes them better able to sneak up on prey.
A.) Give two reasons that the population is not a Hardy Weinberg equilibrium.
C.) How are the allele frequency change in the wolf population
Answer:
A, This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.
b,HW equilibrium means no selective pressures like the long, snowy winters selectively favoring the white coat phenotype over the other coat phenotypes. Selective pressures change the relative frequencies of the alleles in the gene pool. It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift.

Select one:

b. cooler than usual waters in the tropical Pacific
c. warm waters traveling eastward toward South America
d. cool waters causing colder than normal temperatures in the Southeast Incorrect
Answer:
D
Explanation:
I think so
1. Coriolis effect would deflect the path of the air mass to the west.
2. A horizon would provide the best assessment of the fertility of a soil.
3. Label E is located above Label D.
4. A La Niña can be described as cooler than usual waters in the tropical Pacific
The correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
The Coriolis effect is the deflection of moving air (or an object) due to the Earth's rotation. The air moving in the northern hemisphere is deflected to the right of its intended path due to the Coriolis effect. As a result, in the Northern Hemisphere, air masses traveling from high to low latitudes will be deflected west.
The A horizon, commonly known as the topsoil, contains the most organic matter and nutrients, making it the most fertile layer of soil. This is the layer in which organic components such as degraded plant matter and humus interact with mineral particles to provide an optimal environment for plant growth.
The location at latitude D, which lies above the equator and parallel to the top of the Hadley cell, is where you might expect to find the driest average conditions in the Hadley cell circulation pattern mentioned in the question (north of the equator). Due to the compression, the air in the Hadley cell becomes warm and dry as it descends, resulting in arid or desert-like conditions.
La Niña is a climate phenomenon that causes cooling of sea surface temperatures in the central and eastern tropical Pacific Ocean. It represents the inversion phase of the El Niño–Southern Oscillation (ENSO) cycle.
Therefore, the correct options for 1, 2, 3 and 4 are B, B, D and B respectively.

Why are green plants considered producers?
Green plants directly absorb sunlight to make energy.
Green plants contain chlorophyll.
Decomposers consume green plants.
Green plants are eaten by secondary consumers.
Answer:
The organisms that are capable of preparing their own food from simple inorganic substances like carbon dioxide and water by using sunlight energy in the presence of chlorophyll are called producers. The green plants synthesize their own food through the process of photosynthesis and thus are called the producers.plants produce food for themselves, they are known as producers.What are some living and non living things that change mountains over time?

Answer: The correct option is C.
myrmecophytes.
Explanation:
This is because ants and myrmecophytes have mutualistic relationship in which the plants provide food, and accomodation to the ants through the structural adaptations of plants like dormatia, fruiting bodies, nectaries flowers. The ants inturn ahelp the myrmecophyte in pollination, seed dispersal, to defend it against Intruders and also help it to gather nutrients.

what is the advantage and disadvantage of the Ocotillo and Hummingbird relationship
Advantages:
The plant is an integral member of the regional desert ecosystem and native pollinators such as hummingbirds and carpenter bees consume ocotillo nectar for nutrients. The hummingbird and the ocotillo have an important plant-pollinator relationship, as the hummingbird relies upon the flowers for a nectar source.
The relationship between Ocotillo and Hummingbird is an example of a mutualistic relationship, which means that both species benefit from each other's presence.
What are the various advantages and disadvantages of the relationship ?The advantages and disadvantages of this relationship can be described as follows:
Advantages:
Ocotillo provides a source of nectar for hummingbirds, which is an important source of energy for their high metabolic rate.
Hummingbirds are efficient pollinators of Ocotillo flowers, which helps to ensure their reproduction and genetic diversity.
Ocotillo provides a nesting site for hummingbirds, where they can raise their young in safety from predators.
Disadvantages:
The relationship between Ocotillo and hummingbirds is specific and may not be beneficial to other species of plants or animals.
Ocotillo is adapted to living in arid environments and may not provide a suitable habitat for some other species of birds or animals.
If the population of either Ocotillo or hummingbirds were to decline significantly, it could affect the survival of the other species in the mutualistic relationship.
Overall, the advantages of the Ocotillo-Hummingbird relationship outweigh the disadvantages, and this mutualistic relationship is an important part of the ecosystem in which they both live.
