Among molluscs, which of the following traits is associated with cephalization? A) a complete gut B) segmentation C) active predation D) radial symmetry
Among molluscs. the trait associated with cephalization is active predation.
Thus, the correct option is C.
What is cephalization?Cephаlizаtion is the process in аnimаls by which nervous аnd sensory tissues become concentrаted in the "heаd." The evolution of а heаd аllows scientists to distinguish between the heаd end, or аnterior end of аn аnimаl's body, аnd the opposite end, the posterior. Аlthough cephаlizаtion is аssociаted primаrily with bilаterаlly symmetricаl species, even some of the more primitive, rаdiаlly symmetricаl аnimаls show some degree of cephаlizаtion.
All of the members of the mollusc phylum displаy bilаterаl symmetry. So, among molluscs, the trait associated with cephalization is active predation. Because generаlly molluscs do not hаve cephаlizаtion but certаin members gаined this trаit due to their аctive predаtory lifestyle.

Mendel found that the allele for tallness in plants (T) is dominant to the allele for shortness (t). What would possible results be if a heterozygous plant self-fertilizes?
_____ x _____
genotypic ratio: ____ : ____ : ____
phenotypic ratio: ____ : ____
What is the probability of having a homozygous tall plant? _____
When a plant self-fertilizes, is there still genetic variation between offspring and parent? ________
If a heterozygous plant self-fertilizes, the possible results are that the offspring will be either homozygous dominant (TT), heterozygous (Tt), or homozygous recessive (tt).
The genotypic ratio for the offspring of a heterozygous plant that self-fertilizes is 1:2:1, meaning that there is a 1 in 4 (25%) chance that the offspring will be homozygous dominant (TT), a 2 in 4 (50%) chance that the offspring will be heterozygous (Tt), and a 1 in 4 (25%) chance that the offspring will be homozygous recessive (tt).
The phenotypic ratio for the offspring of a heterozygous plant that self-fertilizes is 3:1, meaning that there is a 3 in 4 (75%) chance that the offspring will have the dominant trait (tallness) and a 1 in 4 (25%) chance that the offspring will have the recessive trait (shortness).
The probability of having a homozygous tall plant is 1 in 4 (25%) if a heterozygous plant self-fertilizes.
Even when a plant self-fertilizes, there is still genetic variation between the offspring and the parent. This is because self-fertilization only involves the mixing of the genes that are present in the parent plant, and it does not create new genetic variation. Therefore, the offspring of a plant that self-fertilizes will have the same genetic variation as the parent plant, but the specific combination of genes in each individual offspring may be different from the parent.

What is a nervous impulse?The term "action potential" also refers to the nerve impulse. It speaks of the electrical signal that an activated neuron sends out. Afterward, synapses, or connections between the cells, send this signal.
A neuron is in a resting state when it is not actively delivering a nerve impulse, ready to do so at any time. The sodium-potassium pump keeps a differential in charge across the neuron's cell membrane while it is at rest.
The sodium-potassium pump is an active transport system that transports potassium ions (K+) into cells and sodium ions (Na+) out of cells. Using energy from ATP and carrier proteins in the cell membrane, the sodium-potassium pump transports both ions from regions of lower to greater concentration.
The resting potential is an electrical gradient that results from these concentration changes across the cell membrane. Nerve impulse transmission requires precise control of membrane resting potential.

b. when sources are less than sinks
c. when sources are greater than sinks
d. when anthropogenic sources are greater than
natural sources
e. when anthropogenic sinks are less than
anthropogenic sources
Answer:
a. when sources equal sinks
Explanation:
The difference between sources (emissions to the atmosphere) and sinks determines the change in a gas's concentration in the atmosphere (removals from the atmosphere). Many natural processes remove GHGs (“balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases”) from the atmosphere. In the ocean, carbon dioxide (CO2) dissolves and is absorbed by plants during photosynthesis. In the atmosphere, photochemical processes are principally responsible for the destruction of methane (CH4) and nitrous oxide (N2O).
In addition to naturally occurring biological activities like breathing, human activity also produces these gases. Only when sources and sinks are equal are GHG concentrations stable.

Answer: What do we call variation that can be inherited?
heritable variation
Explanation:
The term for variation that can be inherited is "heritable variation." It refers to traits or characteristics that are passed down from parents to offspring through genes. These traits can include physical features like eye color or height, as well as certain behaviors or abilities.
An example of heritable variation is hair color. If both parents have brown hair, there is a high chance that their children will also have brown hair. However, if one parent has blonde hair and the other has brown hair, there is a possibility that their children could have either hair color, depending on the specific genes they inherit.

Agriculture and fisheries are highly dependent on the climate. Increases in temperature and carbon dioxide (CO2) can increase some crop yields in some places. But to realize these benefits, nutrient levels, soil moisture, water availability, and other conditions must also be met. Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers and threaten food safety.[3] Meanwhile, warmer water temperatures are likely to cause the habitat ranges of many fish and shellfish species to shift, which could disrupt ecosystems. Overall, climate change could make it more difficult to grow crops, raise animals, and catch fish in the same ways and same places as we have done in the past. The effects of climate change also need to be considered along with other evolving factors that affect agricultural production, such as changes in farming practices
