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.

Why do plants have trouble growing in space?
Answer:
The first challenge in growing plants in space is how to get plants to grow without gravity. This runs into difficulties regarding the effects of gravity on root development, providing appropriate types of lighting, and other challenges
Answer:
because, The first challenge in growing plants in space is figuring out how to get them to thrive in the absence of gravity. This presents difficulties in terms of the impact of gravity on root growth, as well as the provision of adequate lighting and other issues.
Explanation:
Gravity has an impact on root formation, but the scientists discovered that their space plants didn't need it to thrive. The space flowers showed common root growth patterns such as "skewing," where roots slant slowly as they branch out, when grown on a nutrient-rich gel in transparent petri plates.

in your own words, what is the definition for Plasmalemma
Answer:
plasmalemma or cell membrane is a biological structure that separates all the cells interior organs from the layer of protection that protects it from the environment (cell wall in plants). this membrane allows osmosis and diffusion to take place within the cell.

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.

Modern humans are the product of evolutionary processes which have occurred over millions of years . True or false?
Sorry for all of this, I’m having trouble with these questions!
Answer:
True to an extent.
Explanation:
Modern humans are the product of evolutionary processes. This is true to some extent.
What is evolution?
Evolution is defined as the theory in biology that various types of plants, animals, and other living things on Earth evolved from other preexisting types and that distinguishable differences are the result of modifications in successive generations.
There are basically four types of evolution.
Divergent evolutionConvergent evolutionParallel evolutionCoevolutionHumans are one of the best example of evolution.
Thus, modern humans are the product of evolutionary processes which have occurred over millions of years. This is true to some extent.

I need a Multiple Alleles trait for an animal!!!
Answer:
Fury can be a allele trait in an animal anything that you can see in the physical appearance on the animal can be a alleles trait
Answer:
Anything you see physically on an organism can be considered as an allele.
Explanation:
An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Let's use one example: a white bunny with red eyes. One allele for this animal would be that it has white fur color. Another allele would be its red eye color.
Let's use another example, but with two people. Person A has straight hair and freckles. Person B has curly hair and no freckles. Person A's alleles would be straight hair and freckles. Person B's alleles would be curly hair and no freckles.
Any physical characteristic trait on an organism can be considered as an allele for that organism.
✎﹏☾✦☁️❣️ Briefly explain the process of photosynthesis .❣️☁️
Answer:
hope this will help u
Explanation:
photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Explanation:
PHOTOSYNTHESIS
This is a process in which green plants and other organisms make their own food from simple inorganic substances which are sunlight ,CO2 and chlorophyll.
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).
