What evidence is there that strands are from a body cell, and not from a gamete
(sperm or egg)?
Answer:
Explanation:
If we are talking about humans:
If you have a diplod genome (2n) (23 pairs of chromosome = 46 chromosomes total) then you have a body cell.
Gametes have haploid genome (n) = 23 chromosomes.
Use this to understand the evidence given to you.
how is a leopard frog like a human?
Answer: They scream when being killed
Explanation:
Leopard frogs (genus Lithobates) and humans (Homo sapiens) are both living organisms and share certain characteristics as part of the animal kingdom.
Few points of comparison between leopard frogs and humans:
1. Classification: Leopard frogs and human beings are both considered to be vertebrates, which means they both have a backbone and are within the phylum Chordata.
2. Body Structure: Both leopard frogs and humans have a bilateral symmetry, meaning their bodies can be divided into two equal halves.
3. Sensory Organs: Both have sensory organs such as eyes, ears, and a sense of touch, allowing them to perceive their environment.
4. Reproduction: Both reproduce sexually, with males and females coming together to produce offspring.
5. Respiration: Humans and leopard frogs both have a respiratory mechanism that enables oxygen inhalation and carbon dioxide exhalation. However, the two species' unique respiratory structures and systems are different.
6. Homeostasis: Leopard frogs and human beings both work to keep their internal environments in balance and homeostasis by controlling things like body temperature, pH levels, and metabolic activities.
Thus, similarities are seen in their body structure, sensory organ, reproduction, respiration, and Homeostasis.

Which statements is true about organ systems in the human body?
Choose 1 answer:
(A) if one organ system fails, a different organ system can take its place.
(B) all organ systems carry out the same functions in the human body.
(C) organ systems interact to allow the body to live and grow.
Answer:
(C) organ systems interact to allow the body to live and grow.
Explanation:
Organs depend on each other to carry out a certain function so the other organs can work.
Example- If the lungs of your body fails there will be no supply of oxygen. If there is no supply of oxygen there will not be enough blood for the heart to function.
If there is no oxygen there will be no oxygen or enough blood to flow to the brain.
Without the heart working the will be no blood to pump throughout the body.
Without the brain there will be no control to have the body and its organs to work properly.
Etc.
It is a chain reaction.

What are three ways in which genes are expressed through adaptations?
Answer:
this my answer and if u are in class 10 then you aslo ask me questions of it ok by Explanation: The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.A new predator is introduced to an aquatic ecosystem. In a population of fish that live there, very small fish are more easily able to hide from the predators, and very large fish cannot be easily eaten by predators. What type of natural selection is acting on the population, and what will be the expected result?
A.Stabilizing selection: Since both extremes are selected against, the fish population will remain about the same.
B.Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, small and large fish will be common.
C.Stabilizing selection: Over time the fish population will change. Medium-sized fish will become rare, small and large fish will be common.
D.Disruptive selection: Since both extremes are selected against, the fish population will remain about the same.
Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, and small and large fish will be common is a type of natural selection that is acting on the given population. So, it's B.
What do you mean by Ecosystem?An ecosystem may be defined as any place or area where the members of different species or communities live together and interact with one another for the purpose of food, shelter, and space.
As predators are only able to attack the moderate-sized fishes, so the population of moderate-sized fishes may decline in the aquatic ecosystem, while extremely short and large fishes are able to maintain their population at the same pace.
Therefore, the correct option for this question is B.

Selective breeding is the result of choosing two parents with certain characteristics in order to produce an offspring that is more likely to possess these traits. Over generations, these traits can accumulate to the point of creating a new breed. To put it simply, all dog species share a common ancestor-the wolf.
what is the relationship between codons and anticodons?
Answer:
Complementary to each other
Answer:
Complementary nitrogenous bases
Explanation:
The codons and anticodons have complementary nitrogenous bases, allowing them to base pair. Because the kind of amino acid attached to a tRNA depends on the tRNA's anticodon, the base pairing between the anticodons and codons brings a specific sequence of amino acids to the ribosomes. For example, the codon labeled F is complementary to the anticodon UAC and codes for the amino acid methionine.

Which property of water causes the space between molecules to ice
Answer:
In ice crystals, their hydrogen bonds link them together like acrobats, stacked one on top of the other, with their arms and legs outstretched. This provides more space between the molecules in the crystal structure of ice than the molecules of liquid water. As a result, ice is less dense than the liquid form

Activity: Write in your own words and understanding how do soil formed and identify the factors that helps in the formation of soil.
don use any searching app in answering
Soil is formed by the weathering of rocks which takes place over millions of years. Hence, soil formation is a slow process.
Soil formation takes place in different layers namely topsoil, subsoil, partly weathered rock and parent rock or bedrock.
The topsoil is rich in humus and supports all types of vegetation. Subsoil consists of sand, silt, clay and holds moisture.
Factors Responsible for Soil Formation :The parent rock determines the colour, the texture and mineral composition.Climate controls the rate of weathering, time decides the maturity of soil.Plants and animals contribute to humus formation and the relief of the land determines the accumulation of soil.Answer:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
