Answer:
Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Darwin noticed that birds that were good at finding scarce food in the winter had a better chance of surviving and producing offspring. What did he call this struggle for existence?
Answer:
Natural selection.

What is the meaning of morant system as used in rabbit keeping?
Answer:
the design of rabbit hutches is based on this system
Explanation:
it provides a mixture of grazing area and a solid floor for sleeping
Answer: Rabbits can be grazed outside when there is plenty of green grass. This system is known as the morant system and in this case, a morant hutch is used. A moran t22 hutch is a basketlike cage which is built and transferred to different grazing areas. Rabbits are omnivorous animals that eat many food types.
write about the circulation of lymph for class 10
Answer:
The lymphatic system is a complex system of fluid drainage and transport, and immune response and disease resistance. Fluid that is forced out of the bloodstream during normal circulation is filtered through lymph nodes to remove bacteria, abnormal cells and other matter.
lymph circulation. The flow of lymph from the tissues into the lymphatic collecting system. ... It is collected into lymph capillaries, which carry the lymph to the larger lymph vessels. These converge to form one of two main trunks, the right lymphatic duct and the thoracic duct.
Understanding the lymphatic system's role in immune cell trafficking and immune responses, contribution to fat transport, distribution, metabolism and implication in the pathogenesis of chronic intestinal inflammation may provide the basis for new therapeutic strategies and improved quality-of life.

Kai has a see-through glass tank with air, plants, and animals that eat those plants. He sealed the tank so no material can get into or out of it, but light can get in when the tank is not covered.
The light for the tank has been on all day, and Kai measured the carbon in the air and found that it is decreasing. How is carbon moving between the air and the living things in the tank? What is happening to the amount of carbon in living things? Explain your thinking as completely as possible.
Answer:
1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis
2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.
Explanation:
According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.
Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).
2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.
1. Carbon is flowing from the living organisms in the tank into the air by the process of respiration and from the surrounding back into plants via photosynthesis.
The animals in the tank utilize the oxygen when they inhale while during exhalation carbon dioxide is liberated. The carbon dioxide in the tank is used by the aquatic plants to produce food and energy in this way the level of oxygen and carbon dioxide is maintained in the tank.2. The quantity of carbon in living, are expanding as plants use this carbon in the process of photosynthesis from the environment and animals consumes those plants.
The deposited carbon in the food gets spent by the animals and they release this carbon back via exhalation. Therefore the quantity of carbon in living things is increasing.To learn more about respiration and photosynthesis follow the link:

Does evolution occur at the individual or population level?
Answer:
populations
Explanation:
this is because individual species are not changing. Populations are evolving. Since people in a group differ, those of the population are more able to live and replicate owing to a specific range of environmental conditions.

Explanation:
the process of evolution occurs only in population and not in individuals . all single individual can not evolve alone evolution is the process of changing the gene frequencies with in a gene pool .
Which energy source contributes least to global warming?
Answer:
ITS D
Geothermal energy is generally considered environmentally friendly and does not cause significant amounts of pollution. ... Harnessing geothermal energy does not involve any fuels, which means less cost fluctuations and stable electricity prices. Small footprint on land – can be built partially underground.
The environmental effects of geothermal development and power generation include the changes in land use associated with exploration and plant construction, noise and sight pollution, the discharge of water and gases, the production of foul odours, and soil subsidence.

10. Which of the following groups of organisms are prokaryotic? (Choose all that apply)
Archaea
Or
Plants
Or bacteria
Or fungi
Answer:
Archaea bacteria
Explanation:
just search each answer choice asking if its eukaryotic or prokaryotic and it will tell you
Bacteria and Archaea are groups of organisms that are prokaryotic, which means that their cells do not have cellular organelles or a delimited nucleus in the cytoplasm.
The prokaryotic cell is characterized by not having a cell nucleus, therefore its ribosomes are smaller and its genetic material simpler.
Prokaryotes are, in most cases, unicellular microorganisms.
The bacteria is a unicellular and prokaryotic microorganism, which means that it does not have a nucleus, they are a few micrometers long and various shapes including spheres (cocci), rods (bacilli) and helices (spirils).
A diversity of unicellular microorganisms that make up the archaea kingdom lacking nuclei (prokaryotes) is known as archaea.
Their cells are surrounded by a covering (cell wall) made of various materials that give them high resistance against antibiotics or other harmful substances.
Therefore, we can conclude that bacteria and archaea are groups of organisms that are prokaryotic, which do not have a defined nucleus and or organelles surrounded by a membrane.

What unusual cellular characteristic does N. locustae share with the protist Mixotricha paradoxa, the organism discussed in the article "A Russian Doll of Symbiosis?"
Answer: Both N.locustae and protist Mixotricha paradoxa do not have a mitochondria.
The mitochondria is a basic cell organelle that palys the role of energy generation for the cell.this energy generated is in the form of ATP.
The organism N. locustae tends to rely on it's host cell that is that grasshopper. This host cell is that in which N. locustae replicates inorder to get a supply of energy.
On the other hand,the organism Mixotricha paradoxa relies on the bacteria endosymbionts to be able to supply it with energy.

Identify the strengths and weaknesses of Mendel’s Law of Independent Assortment.
Answer:
Explanation:
Mendel propel two laws The law of inheritance and that of independent assortment of gene.
Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.
This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.
Pleiotrophy effect of a gene where a gene is having many effects.
