Answer:
Places with latitudes closer to the Equator have hotter climates. Places with latitudes closer to the Poles have colder climates. This happens because the Sun's rays hit them more or less directly.
The Sun powers life on Earth; it helps keep the planet warm enough for us to survive.
What are some indirect changes on Earth from Climate Change
(Greenhouse Emissions)?
a. Coral Bleaching
b. Ocean Acidification
c. Sea Level Rise
d. All of the above
Answer:
The answer is D.All of the above
Answer:
D
Explanation:
1: Coral Bleaching happens when 2 to 3 degree temperature changes.
2: carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
3: sea level rise happens when ice caps or glaciers melt.
4: it's all of them
Bacteria convert the nitrogen in the atmosphere into
a.Usable nitrogen
b.Non-usable nitrogen
Answer:
b. Usable nitrogen
Explanation:
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.

How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?
Answer:
Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.
Explanation:
Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.
To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.
In 1859, Charles Darwin proposed that differential survival and reduction of individuals would produce changes in species population over time. In other words, the environment acting on variation of individuals within a population would result in an adaptation (an evolutionary process that results in morphological, physiological or behavioral changes at the population level and that increases the probability of the members of that population to survive and their reproductive success). Using a specific example, explain how natural selection explains the theory of evolution. Also include in your explanation and within your example, what are the 4 factors needed for natural selection to act
Answer:
Reproduction, heredity, variation in fitness or organisms.
Explanation:
Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.

Explanation:
got it right on edg quiz (see pic)
hope this helps :)
All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
What is the digestive and excretory system?Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.
The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.
The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).
Therefore, the correct answer is a).

similarities between the vas deferens of a male reproductive system and fallopian tube of a female reproductive system are ?
Answer:
Vas deferens → Male reproductive system
Fallopian tube → Female reproductive system.
Explanation:
In vertebrates, there are paired gonoducts for the movement of gametes from the gonads. Humans are no different.
1. Vas deferens is a male gonoduct that transports sperm away from the testes in preparation for ejaculation. Vas deferens collects secretion from seminal vesicle and becomes ejaculatory duct before draining in male urethra.
2. The fallopian tube is a female gonoduct that receives ova from the ovary when ovulation occurs. Fertilization occurs in the fallopian tube, and the early embryo moves from the tube to the uterine cavity.
3. Ciliated pseudostratified epithelium lines the vas deferens, while ciliated columnar epithelium lines the fallopian tube.

Cheests as a species of cat best known for being the fastest land animal, with the ability to sprint at speeds of up to 120
Kilometers per hour, Cheetahs have small heads, lean bodies, long legs, and a yellowish-tan coat with distinctive black spots
Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction, which is reducing the size of
their populations, Predict how these pressures have affected the genetic diversity of cheetahs.
Answer:
Genetic diversity has decreased due to inbreeding due to dwindling population size.
Cheetahs are facing great pressures, such as climate change, destruction of their habitat, and also hunting by humans that have greatly impacted their genetic diversity.
What are the causes of inbreeding in Cheetahs?Cheetahs have experienced a very declining rate of their populations due to destruction of their habitat, and also hunting by humans that has resulted in inbreeding in their populations and loss of genetic diversity.
Due to inbreeding, cheetahs have become more exposed to genetic disorders and vulnerable to diseases, and other threats.
Climate change has also posed a great threat to the declining population of cheetahs as it has affected their habitats and food resources. Climate change causes alteration in the temperature and rainfall pattern resulting in low availability of prey and water resources. Therefore, climate change leads to the malnutrition of cheetahs and making them more susceptible to severe disease.
Therefore, cheetahs are facing extinction due to climate change, habitat destruction, and hunting by humans.

state one adaptation of nephron in the kidney of a desert mammal
Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.
