Why does a cis fatty acid have a kinked shape?
Answer:
Steric hindrance in the cis orientation causes the chain to take on a more bent shape. Most natural unsaturated fatty acids are in the cis conformation. As can be seen in Figure 2.327, the cis fatty acids have a more of kinked shape, which means they do not pack together as well as the saturated or trans fatty acids
Explanation:
What are the two theories that are combined in the synthetic theory of evolution?
The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
Synthetic theory of Evolution The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.
Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

Carla was recently diagnosed with a brain tumour and has since completely lost
her appetite. The brain tumour is likely located in her:
dorsal hypothalamus
lateral hypothalamus
ventromedial hypothalamus
medial hypothalamus
Answer:
hypothalamus
Explanation:

Which of the following is a problem that could result from poor monitoring of free range grazing?
The increased use of antibiotics
The additional exposure of soil layers
The prevention of invasive plant species
The higher rates of mental illnesses in animals
Answer:
The additional exposure of soil layers.
Explanation:
Antibiotics are administered by humans, so less contact with humans won't cause an increased use of antibiotics. The prevention of invasive plant species is not a problem, nor would it be caused by improper management of free range animals. Mental Illness in animals is usually caused by being put in small enclosure or living in poor conditions, not by being allowed free range. Therefore, the answer is the additional exposure of soil layers, since excessive grazing can decimate plant and soil layers.
I hope that helped!
Answer:
The additional exposure of soil layers

Which is an example of a limiting factor that is dependent on population size?
Answer: Food can be an obvious answer because people will not survive without food so they will die. And death means there will be a decrease on population size. So food can be a limiting factor that is dependent on population size.
Answer:
A limiting factor that depends on propulation size is called a density-dependent limiting factor.
Density- dependent limiting factors include: competition, predation, parasitism and disease.
