Answer:
what are the sources bff
Explanation:
Answer:
Rain runoff, groundwater, melting snow.
Explanation:
Rain flows through various paths and goes into lakes, carrying various types of small leaves or soil particles along with it into the lake.
Groundwater can also form lakes and is the source of freshwater.
The melting snow is also the source of freshwater that flows and reaches the nearby ponds or lakes present in the nearby areas.
why are living organisms classified?
Answer: See explanation
Explanation:
An organism refers to a living thing which can react to stimuli, move, grow, has an organized structure, reproduce, and can adapt.
Living organisms can be classified into kingdom, phylum, classes etc. The reason the classification of living organisms include:
1. Gives information about diversity of living organisms.
2. Easy identification of the organisms
3. Shows inter-relationship among the organisms.
4. Helps in understanding the evolution of the living organisms.
living organisms are classified so that it becomes easier for us to examine or study organisms

Hippopotamuses live in Africa’s rivers and lakes. They’re herbivores and coexist with other herbivores and carnivores. Which action could lead to a decrease in the number of hippos?
Answer:
If any of the other carnivores are predator they might eat the hippos. If the other herbivores population incresses there food supply may drop. If there is a drought there habitat will be in danger. Pouchers are also a threat to this animal.

write four different between parenchyma and collenchyma?
Answer:
The major distinction between parenchyma, collenchyma, and sclerenchyma cells is that parenchyma cells are engaged in photosynthesis, storage, and secretion, whereas collenchyma cells support and transport nutrients, and sclerenchyma cells support, protect, and transport water.

Fertilizer sacks have a three- number value called the NPK value written on them. What does the NPK stand for (18-24-12 written on the bag)?
Answer:
it's a label number
Explanation:
Every label carries three conspicuous numbers, usually right above or below the product name. These three numbers form what is called the fertilizer's N-P-K ratio — the proportion of three plant nutrients in order: nitrogen (N), phosphorus (P) and potassium (K).

What is the likely cause for the Cheetah losing genetic diversity?
Answer: Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction, which is reducing the size of their populations. Cheetahs' own genes also pose a challenge to their continued survival

In maize, yellow kernel color is dominant to white, and wrinkled kernel shape is dominant to the smooth form. Considering both of these traits jointly in self- fertilized dihybrids, the progeny appeared in the following numbers: 193 white, genes assort independently? Support your conclusion using appropriate statistical analysis. wrinkled; 184 yellow smooth; 556 yellow, wrinkled: 61 white smooth
Answer:
yellow, wrinkled are high in population whereas white smooth is lower in population.
Explanation:
Due to self-fertilized dihybrids, the offspring are yellow wrinkled, hybrid and white smooth. 556 yellow, wrinkled are high in population because of the dominant allele while on the other hand, 61 white smooth are obtained and less in number due to recessive nature that comes very little in the population. 184 yellow smooth and 193 white, wrinkled are the hybrid offspring that has both different characteristics from their parents.
write at least three difference between arteryand vein with diagram
Answer:
Difference Between Artery and Vein Artery 1. Vessels which carry blood from the heart to various body parts 2. Arteries carry oxygenated blood from the heart except pulmonary artery 3. Arteries have thick elastic muscular walls 4. Valves are absent 5. Blood flows under high pressure Vein 1. Vessels which carry blood from the various body parts to the heart 2. Veins carry deoxygenated blood from the various body parts except pulmonary vein 3. Veins have thin non elastic walls 4. Valves are present to prevent the backward flow of blood 5. Blood flows under low pressurewhat is photosynthesis?

sexual reproduction drives
a)meoisis
b) genetic symmetry
c) reproductive strategies
d) genetic diversity
Answer:
a) Meiosis
Explanation:
Meiosis is a form of cell division that occurs in sexually reproducing animals' germ cells and is utilized to create gametes such as sperm and egg cells. It takes two rounds of division to produce four cells, each with only one copy of each chromosome.

Why is it important that oxygen and carbon dioxide levels be closely regulated in the human body?
A) Both gases are needed for the proper functioning of cell processes
B) Oxygen is needed for cell processes and carbon dioxide is a waste product
C) Both gases are waste products that need to be removed from cells
D) The carbon and oxygen from the gases are needed to build new molecules.
Answer:
B) Oxygen is needed for cell processes and carbon dioxide is a waste product
Explanation:
Cellular respiration refers to the cellular mechanism by which organisms combine molecular oxygen (O2) with organic compounds obtained from foods, it is a chemical reaction that releases 1-energy (ATP), which is used by cells to carry out its functions, 2-carbon dioxide (CO2) and 3-water (H2O). During the gas exchange, O2 is first transported from the lungs to the blood cells, which subsequently deliver nutrients and O2 to all cells of the body. Simultaneously, CO2 diffuses from cells to tissue capillaries, and then this waste product passes from the bloodstream to the lungs where is eliminated.
How do consumers obtain the carbon that they need for their life processes?
They breathe it in from the surrounding air.
They break down the plants and animals they eat.
They absorb it from the surrounding soil.
They absorb it from water through their pores.
Explanation:
They break down the plants and animals they eat
this is because, plants absorb carbon from the atmosphere to grow in the process of photosynthesis, then consumers obtain their food from plants hence obtaining carbon
Answer: B. They break down the plants and animals they eat.

Scientists have developed a new type of margarine that contains plant ingredients. They expect that the margarine will lower blood cholesterol levels. They want to test their hypothesis by comparing the blood cholesterol levels of people who will consume the new margarine with those who will consume regular margarine for a few days. Both groups of people will know which type of margarine they are to consume. Which type of research design will the scientists consider
Answer:
intervention study
Explanation:
The intervention study or research helps to examine the effects of an intervention of an outcome of interest. The main purpose of this type of study is to endenger the desirable of the individuals in need.
Such studies are often prospective.
In the context, scientist who have developed a new margarine containing plant ingredients. The scientists wanted to test the hypothesis whether consuming this new margarine lowers blood cholesterol in the body or not. They gave people to consume the margarine and is doing the research study. Such a research design is called as the intervention study.

Please help me with this! *30 *points Picture included
Answer:
1.) The first picture is mitochondria and the second picture is chloroplast
2.) The second one is only in plants
3.) The first one is found more commonly in animal cells
4.) Glucose & oxygen goes into #1 and releases ATP energy and water & carbon dioxide (waste) during cellular respiration
5.) Sunlight and water goes into #2 and releases oxygen (waste)
6.) The waste product from mitochondria is what the chloroplast needs to perform photosynthesis and vice versa for mitochondria where the waste product from the chloroplast is what mitochondria needs to make ATP energy
7.) They both have folds and membranes because this is how energy is transferred from one place to another.
