How do insects help a plant to reproduce?
Answer: insects helps plants reproduction through pollution, which further leads to fertilization, flower and seed production.
Explanation:
Answer: Many flowering plants have separate male and female flowers. Therefore, they need help transferring the pollen from one flower to another, so they rely on pollinators to help with pollination. A pollinator is an animal, such as an insect or a bird, that transfers pollen from flower to flower. Plants have flowers that attract pollinators in many ways. They produce nectar that birds such as hummingbirds eat. They have bright colors, "nectar guides,” and patterns that look like bull’s-eyes to guide insects, such as bees, into the flower. Once the animal is inside the flower, it gets covered with sticky grains of pollen. As the animal moves from flower to flower, pollen brushes off onto the stigmas of other flowers. Fertilization can then occur to produce seeds.

how is it possible for a mutation not to have any significance
Answer: Silent mutation
Explanation: Silent mutation do not result in a change of amino acid. This is because some amino acids have more than one codon that code for them. For example a change from TTT to TTC will still result to leucine

What is the relationship between natural selection and adaptations?
Question 1 options:
Adaptations and natural selection are separate processes and not related
Natural selection occurs as a result of adaptations within a population
Natural selection is the process leading up to adaptations in a population
Natural selection and adaptations are actually the same thing
The relationship between natural selection and adaptations is natural selection is the process leading up to adaptations in a population.
What do you mean by natural selection and adaptations?The mechanism that makes it more likely that future generations will have advantageous traits is known as natural selection. The trait that adapts to the environment is called adaptation.
The possibility of regular choice is that characteristics that can be passed down permit creatures to adjust to the climate better than different organic entities of similar species.
Many finches perished because their smaller beaks were unable to crack the tough seeds. Through the course of regular determination, the birds that had the option to adjust replicated and flourished, while the others dwindled in number.

Which of the following replicates prior to mitosis
Answer:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
Explanation:
Final answer:
The correct order of mitosis stages is prophase, prometaphase, metaphase, anaphase, and telophase, crucial for ensuring accurate DNA replication and division into daughter cells. DNA replication occurs during the S phase of interphase, before mitosis.
Explanation:
The question inquires about the correct sequence of events during mitosis. Mitosis is a critical process of cell division that ensures the daughter cells receive an exact copy of the parent cell's DNA. The phases of mitosis progress as follows: prophase, prometaphase, metaphase, anaphase, and telophase, followed by cytokinesis. Observations reveal that DNA synthesis, a precursor to this process, occurs during interphase, ensuring that each daughter cell receives a complete set of chromosomes.
As a car is slowed, most of its kinetic energy is converted by the brakes to:
O
potential energy.
O
electrical energy
O
thermal energy
O
chemical energy
When a car is slowed, the kinetic energy is primarily converted to thermal energy due to the friction between the brakes and the wheels. However, in hybrid vehicles, some of this energy can also be converted into electrical energy and stored in batteries.
Explanation:As a car is slowed, most of its kinetic energy is converted by the brakes to thermal energy. This occurs because the brakes use friction to reduce the car's speed, transforming the motion energy into heat energy. This is apparent when after a car is brought to a stop, the brakes can become very hot. This heat is a form of dissipated energy and is no longer available to do mechanical work, such as moving the car.
In the case of hybrid vehicles, this concept is further utilized, where the brakes convert mechanical energy into electrical energy, which is then stored in the battery.

A. 1 inch/year
B. 5 feet/year
C. 5 inches/year
D. 5 miles/year
Please answer I will mark brainliest!!!
Answer:
A
Explanation:
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
"Children, you ....
cross the street if the lights are red!"
should't
should
must
mustn't
Answer:
Mustn't.
Explanation:
Children in this picture are been labelled pedestrians, and it is totally wrong to use the zebra/white road crossing. This is because their are signs for pedestrians which is pedestrian crossing which is suggestive on when to move or halt totally.
In the other words, the red light means to halt totally while the amber means ready while the green signals move; but these all applies to auto operators or bike and motorcyclists. So the children mustn't cross until the pedestrian walk is signalled for movement on it.
Traffic light colors are of different types with their usual meaning.
Red light means the vehicles should stop while the pedestrian can move.
Greenlight means the vehicles should move while the pedestrian should stop. Yellow light means "ready to move"
According to the given question, we can say that "Children, you must cross the street if the lights are red!. Since red represents that the vehicles are not moving, hence the children are safe to cross the road.

Explanation:
as part of the cell cycle a cell produces new daughter cells that are identical to the original cell. during which phase are the two daughter cells physically separated
Answer:
Cytokinesis is a phase in which two daughter cells are separated from one another.
Explanation:
Cytokinesis is a phase in which cytoplasm of the cell is divided into two equal parts after the cell division i. e. mitosis or meiosis. Cytoplasm is a main part of the cell which contains different organelles of the cell such as mitochondria, ribosome, endoplasmic reticulum, golgi bodies, lysosomes and vacuole etc. It also contains nutrients, enzymes and water in large amount.
Final answer:
The two daughter cells are physically separated during cytokinesis, which is the final step of the mitotic phase of the cell cycle.
Explanation:
During which phase are the two daughter cells physically separated? This occurs in the mitotic phase of the cell cycle. Specifically, the physical separation of the two new daughter cells is completed during cytokinesis. First, mitosis divides the duplicated DNA into two sets and distributes them into separate nuclei. Following this, cytokinesis divides the cytoplasm, resulting in two new cells that are genetically identical to the original cell. It's important to note that while mitosis (karyokinesis) occurs in the mitotic phase, cytokinesis can sometimes take place independently, leading to cells with multiple nuclei (multinucleate cells) when cytokinesis does not occur.

what is the primary purpose of the chromosomes in a cells nucleus?
Answer:
They are made of protein and one molecule of deoxyribonucleic acid (DNA). As the genetic material passes from parents to child, the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent.
The primary function of chromosomes lies in the fact that; DNA is tightly packaged within them.
Discussion:
Chromosomes are thread-like biological structures within which DNA is tightly packaged in the nucleus.
Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division.
Each chromosome has a centromere, which divides the chromosome into two portions.
