Which of the following is a disadvantage for sexual reproduction?
A.
Offspring can be produced more quickly than by asexual means.
B.
Genetic diversity makes organisms respond differently to environmental changes.
C.
The offspring is genetically different.
D.
A lot of time and energy is required for making gametes and finding mates.
Answer: D. A lot of time and energy is required for making gametes and finding mates.
Explanation:
A disadvantage of sexual reproduction is that a lot of time and energy is required for making gametes and finding mates.
WHAT IS SEXUAL REPRODUCTION:
Sexual reproduction is a kind of reproduction that involves two organisms. Sexually reproducing organisms produce gametes or sex cells. One organism called the male contributes a gamete called SPERM while the female organism produces EGG. Sexual reproduction ensures that genetic diversity occurs in the offsprings produced as they are genetically different. However, a disadvantage is that it takes a lot of time and energy to make gametes and finding mates.Learn more: https://brainly.com/question/9775272?referrer=searchResults

Explanation:
Based on the energy flow between trophic levels in an energy pyramid how much energy would be expected to be found at the secondary consumer level in this pyramid
Answer:
100J of energy is transferred to the secondary consumers
Explanation:
According to the second law of thermodynamics, energy transfer from one trophic level to another is not usually a 100% transfer of energy. This is because the organisms at each trophic level use energy derived from food substances to carry out its activities.
Only about 10% of the energy obtained at each trophic level is transferred to the next trophic level.
This implies that only about 1000J of energy is transferred to the primary consumers and 100J of energy is transferred to the secondary consumers.

Mitosis maintains complex organisms by which of the following processes?
A) the removal of waste from the body
B) the exchange of gas with the environment
C) the formation of sperm and egg
D) the healing of a cut after an injury
Answer:
In multicellular organisms, individual cells grow and then divide via a process called mitosis, thereby allowing the organism to grow. ... Cellular division and differentiation produce and maintain a complex organism, composed of systems of tissues and organs that work together to meet the needs of the whole organism.

Adapting to Life at Sea: Take a look at this article from Natural History Magazine. Explain the connection between sea snake's diet, the way in which they eliminate nitrogenous waste, and their need for freshwater. Then explain why this makes life (in at least one way) difficult for them in the ocean.
Answer:
They needs fresh water for drinking purpose.
Explanation:
The Sea snakes favorite food is fish and crustaceans. These sea snakes removes nitrogenous waste in the form of ammonia. They can live in salty water but needs fresh water for drinking purpose. This makes life difficult for sea snakes in the ocean because sea snakes needs fresh water to become hydrated and the sea water is salty which they can't drink so they depends on the rainfall for drinking purpose.
The sea snakes excrete their nitrogenous wastes via cloaca and some of it from the skin.
Sea snake
The snake excretes solid as well as liquid wastes from the cloaca but sometimes the flow of excreta gets disturbed due to change in the osmolarity between the environment and the body. The oceanic water is saline which is responsible for changing the osmolarity.This is making their survival difficult in the ocean.

Which factor does not alter the rate of hydrolysis of maltose, a disaccharide?
A.temperature of the environment of the reaction
B.pH of the environment of the reaction
C.number of enzyme molecules present
D.size of the substrate molecule
The factor that does not alter the rate hydrolysis of maltose is the number of enzyme molecules present.
Enzymes are biological catalysts that promote various reactions in the body. Enzymes are specific in their action. Therefore, only an enzyme can catalyze a particular reaction. The enzymes work based on a lock and key model.

To meet a high demand of energy, a new hydroelectric dam is being proposed in an area. Which of the following describes a possible risk?
C. The Dam would produce renewable energy
A. the dam produces no radioactive waste
B. the dam produces no toxic hydrocarbons
D. the dam could harm or destroy aquatic wildlife.
The statement which describes a possible risk due to the construction of a new hydroelectric dam in an area is the dam could harm or destroy aquatic wildlife.
What do you mean by Hydroelectric dam?A Hydroelectric dam may be defined as a dam is a large, man-made construction built to contain some body of water to handle river flow and regulate flooding.
The hydroelectric power dams are responsible for the utilization of the land for construction and due to this, it impacts the wildlife of that particular area.
Apart from this, it changes the habitat for those aquatic organisms which are better adapted before the construction of new hydroelectric dam.
Therefore, the statement which describes a possible risk due to the construction of a new hydroelectric dam in an area is the dam could harm or destroy aquatic wildlife.

When will an atom give up electrons?
When more than half of the outer energy level is filled
When the n=2 level is full
When less than half of the outer energy level is filled
When the outer energy level is full
Atoms give up electrons when less than half of the outer energy level is filled, forming positively charged ions. Noble gases with a full outer shell do not easily give up or accept electrons.
An atom will give up electrons when less than half of the outer energy level is filled. In chemistry, valence electrons are electrons in the outermost shell or energy level of an atom. Atoms tend to gain or lose electrons when the valence electron shells are not filled. When atoms lose their valence electrons, they become positively charged ions. An ion is a positively or negatively charged atom or group of atoms. For instance, sodium atoms give away one electron to form sodium ions with a positive charge because the outermost shell of sodium has only one electron, which is less than half the number needed to fill the shell entirely. When more than half of the outer energy level is filled, atoms are reluctant to give up their valence electrons, which is why noble gases do not form chemical bonds easily. When the outermost shell of an atom is full, it is stable, which is why noble gases do not give up or accept electrons quickly. Therefore, an atom will give up electrons when less than half of the outer energy level is filled.For more questions on electrons
