Which of the following statements are true about mutations??
1-Mutations are random
2-Mutations are mostly beneficial
3-Mutations can occur in both DNA and RNA
for an organism
4-Mutations can only occur during interphase.
5-Not all DNA codes for proteins
6-Not all genes are turned on or activated
7-Substitution mutations typically result in frameshift
8-Mutations can be genetically inherited
Help!
*I think it is 1-2-4-5-7-8
Mutations are mostly random, Mutations may be found in DNA and RNA, Not all the DNA codes for the proteins, some genes are turned on or activated, Substitution mutations typically result in a frame-shift, They can be genetically inherited.
A mutation is an alteration in the genome of the organisms and may be formed in the RNA or the DNA. These can result from the changes in the genetic make up of the genes. They may also prevent the genes from functioning. Mutation is a process that involves the duplication in DNA through the genetic recombination. A type of genetic engineering.Hence these mutations are random, occurring both in DNA and RNA. Leading to changes in genetic codes and not all genes are activated. Some are inherited. Thus the correct statements are 1, 3, 5, 6, 7, 8.

Answer:
Deficiency of proteins, carbohydrates and fats results in protein-calorie malnutrition (PCM) or protein-energy malnutrition (PEM). PEM occurs more frequently among infants and children between 1-5 years and is an important cause of childhood sickness and mortality.
Which of the following describes how the amount of available energy changes from one trophic level to another? A) Available energy increases as trophic levels indrease. B) Available energy decreases as trophic levels increase. ) Available energy increases from producers to primary consumers, and then decreases. D) Available energy remains the same from one trophic level to the next E) Available energy decreases as trophic levels decrease.
Answer:
B) Available energy decreases as trophic levels increase.
Explanation:
Each time an organism consumes energy, it absorbs it. When it dies the energy is released and only some of it is consumed the organism that eats the first organism. This continues and by the end there is very little energy left because most of it was released into the world.
Answer:
B. Available energy decreases as trophic levels increase

photosynthesis in plant is chemical reaction give reason
Answer:
[tex]\boxed{\boxed{\sf Photosynthesis}}[/tex]
Photosynthesis is a chemical reaction as in this the nature and identity of initial substance changes and new substance form.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Here oxygen is the by product.
STEPS IN PHOTOSYNTHESIS Absorption of light energy by stomata Transportation of water by XylemConversion of sunlight energy into chemical energysitting of water molecules into h2 and o2 Reduction of h2 Formation of CarbohydratesPlants also respire in day time the carbon dioxide is use in the process of respiration and in night it releases in the atmosphere
Photosynthesis occurs only in day time as sunlight is needed in it
The food is stored in leaves in the form of Glucose. The by product oxygen is releases into atmosphereAnswer:
Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved: water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.
During the photosynthesis process, plants capture light energy and use that energy to make glucose. Another product of this reaction is oxygen, which is released as a gas. Here is the chemical equation for photosynthesis: ... During respiration, sugar is broken down in a chemical reaction with oxygen.
The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process
In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.
In one year, 35 giraffes are born to a population. What does this number represent? growth rate emigration immigration birth rate
Answer:
birth rate
Explanation:fgyouyhgbfvtyoluhjjfygtpigubly
The number 35 represents the birth rate of giraffes in the population, specifically the number of giraffes born within a one-year time period and the correct option is option 1.
Birth rate is a fundamental demographic measure that quantifies the reproductive output of a population. It provides insight into the rate at which new individuals are added to the population through reproduction.
In the context of giraffes, a birth rate of 35 indicates that 35 offspring were born during the specified period. This information is crucial for understanding the dynamics of the giraffe population and its potential for growth.
Birth rates, along with other demographic factors such as death rates, immigration, and emigration, contribute to the overall population growth rate.
By examining birth rates over time and in conjunction with other factors, researchers can assess the sustainability and health of a population and make informed decisions regarding conservation and management strategies.
Thus, the ideal selection is option 1.

Look at the offspring you created in your model. Have any of the offspring inherited a more beneficial genetic combination than the others? How could this affect their survival? Explain your reasoning.
Answer:
Yes.
Explanation:
Yes, More beneficial genetic combination of the offspring has a positive effect on the survival of that offspring because due to more good characteristics the organism is able to survive harsh environmental condition and increases its survival rate. So we can conclude that presence of more beneficial genetic combination in the offspring greatly affect its survival in the environment among other offspring.

Why is an organism that reproduces asexually genetically identical to its parent
Answer:
Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.

How do organisms use carbon-based molecules and make water
C6H12O6+6O2--->6CO2+6H2O
This is the equation for cellular resipiration this is how organisms use carbon-based molecules(glucose) and make water
we have that from the Question"How do organisms use carbon-based molecules and make water" it can be said that
The Phenomenon of cellular respiration sees glucose catabolized into water H_2O
[tex]C_6H_{12}O_6+6O_2---6CO_2+6H_2O[/tex]
From the Question we are told
How do organisms use carbon-based molecules and make water
Generally the equation for how carbon-based molecules make water is mathematically given as
[tex]C_6H_{12}O_6+6O_2---6CO_2+6H_2O[/tex]
Therefore
It is seen that cellular respiration is the concept in play here
