Answer:
The atmospheric temperature decreases when snow starts melting because the snow absorbs thermal energy from the atmosphere to melt.
Explanation:
The temperature of the air, the intensity of the sun, the speed of the wind, and the amount of humidity are the factors that influence the melting of the snow. The thermal energy in the atmosphere is absorbed by the snow because the temperature of snow is less than the temperature of the atmosphere. When the flow of temperature takes place, the energy also flows. The thermal energy helps the snow to melt because the snow requires warmth to melt.

Explanation:
Kangaroos are mammals that lack a placenta. Therefore, they must have an alternate way of supplying the developing embryo with
Answer: yolk sac
explanation:
the placenta does not develop for a long time so the alternate way of supplying the developing embryo is through the yolk sac which the embryo can receive nutrients and respiratory gas exchange through which the placenta will be formed later.
Kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.
What is the function of the placenta in pregnancy?The placenta is an organ that develops during pregnancy to provide nourishment to the growing fetus and to remove waste products from the baby's blood and is attached to the wall of the uterus and connected to the baby by the umbilical cord, it is responsible for producing hormones that maintain the pregnancy, such as progesterone, which helps to keep the lining of the uterus thick, also produces human placental lactogen, which helps stimulate the mother's mammary glands to produce milk.
Hence, kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.

State three things you do each day that affect the environment around you. Explain how the things you do affect the environment around you.
Answer:
Driving or using cars as a method of transportation increases the amount of Co2 released into the atmosphere. Due to this the environment becomes less and less unstable. Another daily thing I do every day that effects the environment is throwing away trash. As our trash fills the landfills some of them can be picked up by birds or even end up getting blown into the ocean. However, recycling is one positive aspect in our every day lives. When we recycle companies and factories are able to reuse things we no longer use. Because of this we are able to protect many ecosystems and the environment.

binary fission asexual reproduction in which a single cell divides into two with no exchange of genetic material; reproduction method of bacteria
budding A kind of asexual reproduction involving the growth of a new individual from part of an older organism. It can also refer to uneven distribution of cells that results in one cell receiving most of cell contents. In grafting, budding involves reducing the scion to a singular bud.
central disk = The central portion of a starfish. The arms of a starfish radiate from the central disk.
colony = A group of organisms attached to one another after undergoing asexual reproduction from a common parent.
conidia = A special kind of asexual spore found in many kinds of fungi.
multiple fission = A kind of asexual reproduction in which a single cell undergoes many mitotic divisions in the nucleus and a number of daughter cells are produced all at once.
propagation = The act of propagating or establishing and growing new plants.
protist = A one- or few-celled organism with chromosomes. Many have characteristics of both animals and plants.
regeneration = A phenomenon in which organisms break into two or more parts and then each part grows into a new individual.
