Answer:
Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.

Why do few plants grow in the tundra?
Answer:
In the Arctic tundra, warmth and sunlight are in short supply, even in the summer. ... Only plants with shallow root systems grow in the Arctic tundra because the permafrost prevents plants from sending their roots down past the active layer of soil. The active layer of soil is free from ice for only 50 to 90 days.
Explanation:
The harsh winter climate and lack of sunlight make it hard for plants to grow.
sunlight and warmth is a necessity for plants to grow and make nutrients to survive.

The shift from the Miocene, which had greater diversity of ape species and fewer monkey species, to a living assemblage with greater diversity of monkey species and fewer ape species may be the result of __________.
Answer:
A differential ability to exploit habitats after global climate change
Explanation:
According to the evolutionary theory proposed by Darwin (1859), it is not the strongest nor the most intelligent who survive, but those that are most adaptable to change. The animals that disappeared during the Miocene, a geological epoch from around 23 million years ago to 5 million years ago, likely failed to adapt to changes in environmental (temperature and vegetation) conditions. During this epoch (Miocene), a more severe climate and coarser vegetation likely contributed to the extinction of several mammal species (e.g., species of apes) and diversification of others (e.g., the divergence between chimpanzee and hominid lineages).

Stars are hot objects and give off heat and light. Scientist can collect this energy and tell what two things about stars (even though we cannot observe or measure the star directly).
a.composition
b.temperature
c.exact mass
d.shape
Answer: A or c
Explanation:
Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.
What is Stars?A star is the most well-known celestial object and the main building block of galaxies. The age, distribution, and composition of a galaxy's stars can be used to determine the galaxy's history, dynamics, and evolution.
In addition, stars generate and disperse heavy elements like carbon, nitrogen, and oxygen, and their characteristics are strongly tied to those of any planetary systems that may develop around them.
The study of the origin, development, and death of stars is thus at the heart of astronomy.
Therefore, Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.

What characteristics do you think an animal would have in order to survive in the savanna environment?
Answer:
The type of biome that is made up of scattered grasses and small tress and shrubs is called the savannah. The ecosystem consisting of small community of plants and animal on a large piece of land is is called a biome.
Because the tress are small and scattered this enable the grasses to thrive in the savannah. They are located in the hot and warm climate across the world with the annual rainfall of 50.79 to 127 cm per year. This is estimated t be about 100 '' of rainfall per year .This is fall within certain months, and there may be fire outbreaks when the rain stops or in droughts.
Therefore lack of moisture is the features of the savannah. Plants and animals in this terrestrial biome must develop adaptive features for water conservation to survive with little exposure of the to heat and sunlight to prevent excessive dehydration.
The plants have narrow leaves to reduce the surface area to volume ratio exposed for transpiration and evaporation of moisture
some have underground stem and root for storing starch and water.
Cactus is an example of plant with thick stem to conserve water ,and spikes to prevent been eaten by herbivores
The animals have good stamina to withstand dehydration, and are less active duding the day to conserve body water, and do reduce exposure to the hot and arid environment.
Elephants has wrinkle skin to reduce water loss ,and large ears to dissipate heat.

During an El Niño event, farmers in the southwestern United Stated often benefit from which of the following climatic changes? Longer and cooler summers that increase crop yield
Answer A: Longer and cooler summers that increase crop yield A Wetter and warmer weather that increases soil moisture
Answer B: Wetter and warmer weather that increases soil moisture B Cooler and drier conditions that help cold-weather crops
Answer C: Cooler and drier conditions that help cold-weather crops C Warmer and drier weather that reduces soil erosion and flooding
Answer:
The answer is "Wetter and Warmer weather that increases soil moisture".
Explanation:
During the El Niño event, growers inside the southwestern of the USA often profit from hot weather and much more global warming in moisture in the soil.
Its surface waters were considerably warmer than usual in the eastern Pacific Ocean. Its transition is tightly linked with the atmosphere as well as the winds around the large Pacific.

Would it be justified to call Kreb's Cycle the central wheel of metabolism? Why? Provide two specific pieces of evidence to support your answer.
Answer:
Yes.
Explanation:
Kreb's Cycle is considered as the central wheel of metabolism because the fuel molecules are oxidized ultimately within the Krebs Cycle and its intermediates are used for various biosynthetic pathways. The main function of the Kreb's cycle is to produce electron carriers that can be used in the cellular respiration for producing energy molecules in the form of ATP. without Krebs's cycle, the cell produces only two ATP molecules which very low.
