Answer:
Active Transport
Explanation:
active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Nucleic acids are the organic compounds that control the making of _____ and contain the ______ to pass to the next generation.
Answer:
making of proteins
genetic material to pass to the next generation
Nucleic acids are the organic compounds, which control the making of proteins and contain the genetic material to pass to the next generation.
• The two prime kinds of nucleic acids are ribonucleic acid or RNA and deoxyribonucleic acid or DNA.
• The genetic material found in all the living species is the DNA, which is found in the nucleus of eukaryotes and is found in free-floating form in the cytoplasm in prokaryotes.
• This genetic material is passed on from generation to generation.
• The other kind of nucleic acid is RNA, which is mainly involved in the synthesis of proteins. The types of RNA, that is, tRNA, mRNA and rRNA takes place in the synthesis of protein and its regulation.
Thus, the given blanks can be filled with proteins and genetic material.

Answer:Madagascar Pochards
Explanation: The Madagascar Pochard, or sometimes known as the Madagascan pochard, is a very rare diving duck of the genus Aythya. Thought to be extinct in the late 1990s, individuals of the species were recovered in 2006 near Bemanevika, Madagascar, at Lake Matsaborimena. The species is only found in Madagascar's interior marshes, where it is endemic. The sole wild populations are currently found in Lake Sofia and Lake Matsaborimena. Meanwhile, there are slightly over 50 pochards at Bemanevika.

The observable trait appearing probability for cross-breeding is the phenotype ratio in a Punnett square.
What is cross-breeding?The act of creating offspring, particularly through the mating of two purebred individuals who are from different breeds, variations, or even species, is known as crossbreeding. The practice is specifically referred to as designer crossbreeding because it is typically done with the intention of developing offspring that would acquire desired qualities of the parent lineages. Breeders frequently engage in this approach, particularly when the intended qualities will be advantageous to the progeny, such as when its biological fitness is improved.Hybridization and crossbreeding are sometimes used interchangeably. But specifically, hybridization is the act of creating hybrid offspring by mating two parents from different species.To learn more about cross-breeding, refer to

How does the biodiversity in a food chain compare to the biodiversity of a food web?
Answer:
ExpWhat is Biodiversity?
Biodiversity and food webs
Biodiversity is referred to as the web of life because many microorganisms, plants and animals interact with each other. The relationship among species is an important part of biodiversity.
A food chain is a sequence of who eats whom. The usual order of a food chain is sunlight, plants, herbivore, omnivore and/or carnivore. In one type of farming food chain, green grass and wildflowers use sunlight to grow in a field maintained by a farmer called a pasture. A Billy (boy) or Granny (girl) goat grazes on these delicious plants in the pasture. A goat or any other plant-eating animal is called an herbivore. Animals that rely on the farmer for food and protection are domesticated. In turn, the goat provides milk, meat and wool for the farmer, his family, and others. Humans are omnivores, as they eat plants and animals. The goat also provides fertilizer. Microorganisms decompose the goats’ poop or excrements, which provides fertilizers for the grass and flowers to grow. This is one example of a simple food chain based only on green plants, goats, microorganisms and humans. Millions of food chains exist around the world. Food Chain
Food chains that are related in an ecosystem form a food web. In forest ecosystems, many types of herbivores eat the trees and other plant life. Carnivores, or meat-eating animals such as tigers, lions, and wolves, prey on herbivores. They usually prey on wild animals. Sometimes, if the habitats or homes of carnivores are destroyed, they may also attack goats, sheep or cows for food. For example, in India, farmers may lose their goats to tigers; in Eastern Africa, cows may provide lunch for lions and in Western Canada, wolves sometimes attack the domesticated sheep. Carnivores are an important part of biodiversity because they regulate herbivore populations so that they do not eat their favorite plant species to extinction.lanation:

there are many contributors to malnutrition and hunger; however, one factor stands out among all others. what is the primary cause of malnutrition?
Irrespective of the fact that hunger and malnutrition has many contributors, one of the leading factors that is regarded as the primary cause of malnutrition is: poverty.

There are several factors that contribute to malnutrition and hunger, however, a leading cause that seem to be the genesis of malnutrition and hunger is poverty.
Poverty can be defined as a state of lacking the means to meet basic daily needs which includes good nutrition.
Most of the countries that are very impoverished have high percentage of their populace suffering from malnutrition and hunger.
When the means is not available to get adequate and quality food, hunger and malnutrition will always prevail against every other contributors.
In summary, irrespective of the fact that hunger and malnutrition has many contributors, one of the leading factors that is regarded as the primary cause of malnutrition is: poverty.Learn more here:

A student made a model of an onion skin cell she viewed
using a microscope. The scale is 500:1. The student's cell
model has a length of 15 cm.
How many centimeters is the real cell's length?
A. 7500 cm
B. 0.002 cm
C. 33 cm
D. 0.03 cm
If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm
