"Female chimpanzee walks away when male chimpanzee approaches" is the one note excerpt from his recent trip to the zoo among the following choices given in the question that would be good to include in his study. The correct option among all the options that are given in the question is option "c".

Correct answer: C). Female chimpanzee walks away when male chimpanzee approaches

The male chimpanzee spends most of their time in a community in which they are born. In contrast to male-female chimpanzee live their group after their birth to join the neighboring group when they are mature.

Female chimpanzee is known to spend their most of the time their child or with the other female rather than the male. Female chimpanzee is known to form, a coalition against a bullying male.

Hence, the correct answer would be option C.




Adaptive melanism describes selection for

Answers

Melanism related to the process of adaptation is called adaptive. Most commonly, dark individuals become fitter to survive and reproduce in their environment as they are better camouflaged. This makes some species less conspicuous to predators, while others, such as black panthers, use it as a foraging advantage during night hunting.Typically, adaptive melanism is heritable: A dominant gene, which is entirely or nearly entirely expressed in the phenotype, is responsible for the excessive amount of melanin.

Adaptive melanism has been shown to occur in a variety of animals, including mammals such as squirrels, many felines and canids, and coral snakes. Adaptive melanism can lead to the creation of morphs, the most notable example being the peppered moth, whose evolutionary history in the United Kingdom is offered as a classic instructional tool for teaching the principles of natural selection.

C

Explanation:

Earth receives thermal energy from the sun via radiation. Which of the following is a result of this energy transfer?A. There is matter to produce carbon compounds on Earth.
B. Earth is a closed system in terms of energy.
C. There is energy to support life on earth.
D. Energy is created but not destroyed in the earth system

Answers

Answer: C. There is energy to support life on earth.

The earth receives thermal energy from the sun via. radiation. This energy is captured by chlorophyll pigments of plants and other organisms to conduct photosynthesis. The sunlight energy is necessary for synthesis of food in the form of glucose. The glucose is converted into chemical form of energy as ATP which is required for respiration process in plants. Photosynthesis and respiration both are necessary processes to sustain life of plants, which further support life of other living organisms. Therefore, energy transfer support life on earth.  

C.) There is energy to support life on earth

Which of the following must unicellular organisms do to maintain homeostasis? A. Specialize cells to perform specific functions
B. Organize cells into tissues
C. Use chemical signals to communicate between its cells
D. Change food or sunlight into useful energy

Answers

The answer is C. Homeostasis is the process within a cell which aims at maintaining equilibrium within the cell. All living cells exhibit this process. Homeostasis happens by detecting and responding to slight changes in the normal processes inside the cell. Homeostasis occurs by regulating the movement of substances in and out of the cell to maintain a stable concentration inside the cell. It uses chemical signals to communicate between its cells.

jeremy is digging in the garden. he feels the spade hit a rock and stops digging immediately. explain how sensory, relay and motor neurons would function in this situation.

Answers

relay neurones allow sensory and motor neurones to communicate with each other. They would decide how to respond to the sensation of the spade hitting the rock by acting between the sensory and motor neurones.

Final answer:

In the situation where Jeremy is digging in the garden and feels the spade hit a rock, the functioning of sensory, relay, and motor neurons is crucial in his body's response to this stimulus.

Explanation:

When Jeremy was digging in the garden, he felt the spade hit a rock. This is sensation was facilitated by sensory neurons which picked up the external stimulation and sent the information in the form of electrical impulses from the nerves in his hands towards his spinal cord and brain. This sensory information travels to the brain via relay neurons, which are also known as interneurons. They reside within the central nervous system and transmit the signals from sensory neurons to appropriate areas of the brain for processing.

Upon processing the sensory data, the brain forms a motor response which is relayed back towards the muscles in his arms to stop digging. The 'stop digging' response is sent through motor neurons, which transmit the signals from the brain to the muscles in Jeremy's arms, causing him to stop the movement of the spade.
