In a particular plant, having smooth seeds is a dominant trait. Having wrinkled seeds is a recessive trait. Two plants with smooth seeds would have what kind of offspring?
A.
The offspring must have smooth seeds.
B.
The offspring may have smooth or wrinkled seeds.
C.
The offspring must have wrinkled seeds.
D.
The offspring have a 25% chance of having smooth seeds.
The statement 'offspring may have smooth or wrinkled seeds' is correct about the offspring of two plants with smooth seeds.
What is a dominant trait?In genetics, a dominant trait is a phenotypic feature associated with the expression of a dominant allele.
An individual can exhibit a dominant trait and be heterozygous for the trait, thereby its offspring can exhibit the recessive trait.
In conclusion, the statement 'offspring may have smooth or wrinkled seeds' is correct about the offspring of two plants with smooth seeds.

What element is group 5 period 7
Group 5 contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.
The element in group 5, period 7 is Nihonium (Nh). It has the atomic number 113.
What is Nihonium?Nihonium (Nh) is a chemical element with the symbol Nh and atomic number 113. It is a synthetic element and was first synthesized in 2003 by a team of scientists at the RIKEN institute in Japan. Nihonium is a member of the group 5 elements, also known as the Nitrogen group, and is located in the 7th period of the periodic table.
It is a highly unstable element and has only been produced in very small quantities for scientific research. Due to its short half-life, it does not occur naturally on Earth. It is also known as Ununtrium.

Why do you think social insects are among the creatures that use pheromones?
Answer:
Explanation:
Social insects use pheromones to send messages to other members of their colonies. Ants leave pheromone trails that lead other ants to food sources. Certain species of honey bees release pheromones when they are injured or attacked to signal other members of the hive that there is danger, or that the hive is under attack.

How does humans affect the moth population?
How does the moth population be affected?
Answer:
Before the industrial revolution, there wasn't much pollution/soot, and the moths were mostly light colored. When humans started using machines for everything, soot coated the trees and the light colored moths were easier for birds (predators) to see. The moths became mostly dark colored, because it was better camoflauge.
Now that we have environmental restrictions, there isn't as much soot everywhere. Now moths are mostly light colored again, because the dark moths are easier to see.

(B) Placing plants in phosphorus rich environments and monitor their growth compared to plants placed in an environment without phosphorus.
(C) Placing plants in hypertonic environments and monitor their growth compared to plants placed in a hypotonic environment.
(D) Monitor the energy level of earthworms where one group has very few mitochondria and therefore lower levels of ATP synthase.
Answer:
Monitor the energy level of earthworms where one group has very few mitochondria and therefore lower levels of ATP synthase.
Explanation:
I did the quiz.
The experimental design that would provide students with information about how the presence or absence of enzymes affects organisms is as follows:
Monitor the energy level of earthworms where one group has very few mitochondria and therefore lower levels of ATP synthase.Thus, the correct option for this question is D.
What are Enzymes?Enzymes may be defined as biological catalysts that assist in increasing the speed of the biochemical reaction inside the body of living organisms. Such types of compounds regulate the process of biochemical reactions without being consumed in them.
Among the options given above, the mitochondria is a type of cell organelle that produces energy in the form of ATP with the action of an enzyme known as ATP synthase.
If this enzyme is present in a normal amount, then the synthesis of ATP or energy is normal for the organism. But if this enzyme is lower than the actual level, it is found that mitochondria would not produce sufficient energy.
Therefore, the correct option for this question is D.

Plum Island is divided into two diverse areas. (A) What are the differences between the two sides? What are the relative fractional sizes of the sides. (B) During a storm what are the differences in effect on the flora and base of the island?
Plum Island is divided into two different areas, the differences between the two sides are few, but one was human activity and the other was not.
During a storm, what are the differences in effect on the flora and island base?
On the one hand, being more preserved than the other, soil erosion will be lower on the side with greater vegetation, and the area where there was human activity suffers more from strong winds and rains.
With this information, we can conclude that Plum Island is divided into two different areas, the differences between the two sides are few, but one was human activity and the other was not.

PLEASE HELP!! ASAP favorable adaptations are genetic mutations that
A are acquired by increased use of an organ
B improve the organism’s chances of survival
C cannot be passed on to the next generation
D reduce the organism’s chances of survival
Answer:
[B] improve the organism’s chances of survival
Explanation:
Favorable adaptation are individual better suited to survive and reproduce in their environment. Meaning that will become more and more common in the population. Which also means they increase an organism's chances of surviving or reproducing, so they are likely to become more common over time.
Basically, improve the organism's chances of survival and reproducing. As a result we can see that the best answer choices is [B] improve the organism’s chances of survival

Are plant cells shaped so they can stack?
Answer: Yes
Explanation:
Plant cells come in all shapes and sizes. Some are round, some are brick shaped, others look like shoe strings. The one thing they have in common is a rigid cell wall. This means that they cannot change shape very easily. The straight, strong walls give the plant cells tensile strength and allow them to stack on top of each other. This enables plants to grow upwards.
