d. plant cover
Factors that limit population size are space, food, shelter, water, climate, competitive exclusion, and temperature. This means that the carrying capacity of an ecosystem, which is the total number of organisms it can support, will be limited. They can be abiotic or biotic. Abiotic factors that limit this capacity include sunlight, temperature, chemical environment... while biotic factors include food, predators, disease, competition for resources.
The abiotic limiting factor from the choices below is water. Correct answer: C
b. hypothalamus
c. cerebrum
d. forebrain
Thalamus of central brain regulates emotions and thinking process of the body. It is involve emotional processing and arousal functions are functions of the thalamus. Thus, option A is correct
The are several components of human brain like cerebrum, cerebellum and brainstem.
A structure called diencephalon present between two hemispheres of cerebrum which has a structure like thalamus,hypothalamus, subthalamus, epithalamus.
Thalamus is a gray matter responsible for sensory and motor activities, alertness, consciousness or wakefulness in humans.
Hypothalamus is a small part of the brain regulates internal balance, send signals to the pituitary gland to produce hormones, regulates heart rate, blood pressure, body weight, appetite, body temperature and sleep cycle.
Certain hormones secreted by hypothalamus are oxytocin, Anti -diuretic hormone, Gonadotropin, Prolactin hormone etc.
Hence, option A is correct

Explanation:
b. All female offspring inherit their mother's mitochondria, and therefore the same mitochondrial DNA.
c. As a result, all female family members that share a maternal lineage would have the same mitochondrial DNA.
d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
e. All offspring inherit their father's mitochondria, and therefore the same mitochondrial DNA.
Answer:
a. Mitochondrial DNA is inherited through the maternal lineage.
d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
Explanation:
DNA is the genetic material. Nuclear DNA profiling is used to identify a person since each individual has unique DNA. Mitochondrial DNA exhibits maternal inheritance. All the offspring of a female share the same mitochondrial DNA. Therefore, all the individuals that are related by maternal lines, share the same mitochondrial DNA. The profiling of their mitochondrial DNA would not allow the identification of a person when individuals share maternal lines.
