Respiration is a complicated process broken into several steps, but only two reactants are used up in the
reaction and only three molecules are produced, Identify the reactants and products and describe the steps in
which they are used or produced.

Answers

Respiration is the process by which people (and other organisms) break down glucose (from sugars and charbohydrates in their food) in order to release energy. This process requires oxygen which we breath in.

Respiration occurs in almost every cell in the body because the whole body needs energy.

The energy is released in the form of a molecule called ATP which is easily broken down to provide energy when needed.

This energy can then be used for movement (muscle contractions) and other uses in the body, like making and transporting molecules.

Water and carbon dioxide (which we breath out) are also produced during respiration.

So, the chemical equation for resperation is:

glucose + oxygen --> water + carbon dioxide (+ energy)

Would collecting the resources that go into bread have long-term or short-term effects on the environment? Explain your answer.

Answers

Answer:

a short term effect. In their life cycle analysis, the researchers found that a loaf of bread emits about a half-kilo of carbon dioxide. Forty-three percent of bread's greenhouse gas emissions can be attributed to the fertilizers used to grow wheat

It is a short term effect. In their life cycle analysis, it has been observed that a loaf of bread emits about a half-kilo of carbon dioxide.

What's the Environmental Impact of a Loaf of Bread?

The life cycle of a loaf o bread is started from growing, harvesting, and transporting to producing flour, shipping to a bakery, baking loaves and packaging them.

In the life cycle it has been found that per loaf of bread about a half-kilo of carbon dioxide is emitted where nearly 43%  of bread’s greenhouse gas emissions can be  used in the fertilizers for wheat cultivation.

Two-thirds of the emissions come from actual fertilizer production.

we are unaware of the environmental impacts of this products mainly concerned with human health or animal welfare.

It was found that  each loaf production is associated with  global warming as a result more amount of fertilizer applied in order to increase their wheat harvest.

1. The father is a non-roller, as was given in the question. Remember that a phenotype is the physical trait displayed by an organism.

2. In order for the father to be a non-roller, the recessive non-roller allele would have to be expressed. In order for this to happen, he would need two recessive alleles.

3. The gene for tongue rolling is dominant, so if the mother is heterozygous (she has one dominant allele and one recessive allele), then she will be a tongue roller.

4. The mother has a dominant allele and a recessive allele.

5. 50% of the offspring have the Rr genotype and 50% have the rr genotype. This means that there is a 50% of having a tongue-rolling child and a 50% chance of having a non-rolling child.

6. Because the possibility of the offspring having either genotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.

7. Because the possibility of the offspring having either phenotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.

The process of evolution, or genetic change over time, has resulted in the wide variety of living things that exist today. What part do mutations play in the evolution of species

Answers

Answer:

Evolution has occurred thanks to many random changes in the DNA base sequence that we call mutations. This is caused by errors in the genetic information contained in the cells - due to chemical or physical factors - and also its subsequent propagation by replication, being transcendent for evolution those that will later be transmitted to the offspring: somatic cells if reproduction it is asexual and the gametes if it is sexual. For this reason, we say that mutations are the primary source of gene variability, essential for evolution to exist. Thus, without mutations, the genetic variability that natural selection needs would not be present - in addition, such diversity is important for the population to more successfully mold (or adapt) to continuous environmental changes.

Explanation:

A mutation is a change in the information contained in the DNA of cells. The DNA of an organism influences all aspects of its life. Therefore, a change in the DNA of an organism can produce changes in all aspects of its life. The mutation increases the genetic variability of the species and contributes to the adaptation of the species to the environment and to their evolution. Viability and fertility are associated with adaptation, the total capacity of an organism to survive and reproduce. The effect of a mutation in any generation is minimal, but over time a considerable amount of variation from mutations can accumulate. Most mutations are harmful and their carriers die, but those that produce an improvement remain in the species and are essential in the evolutionary process. When mutations appear in a certain population, the genotype changes from generation to generation, appearing individuals with characteristics different from those of their predecessors. This is how the population evolves, being able to originate new species. Mutations that are detrimental to the carrier individual will be eliminated by natural selection.

A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?

Selective pressures will decrease the number of brown beetles.

Selective pressures will increase the number of brown beetles.

Selective pressures will decrease the number of black beetles.

The overall size of the beetle population will continue to decrease over time.

Answers

Answer:

the first option

Explanation:

As the soil gets darker, brown beetles become easily recognised by predators (like birds) and will be eaten. Black beetles however, are better camouflaged and will less likely be spotted by the birds. Black beetles will survive and interbreed, allowing the recessive allele to be passed on to upcoming generations.

Selective pressure is what makes the genetic pool shift toward a particular genotype with a particular phenotype (recessive black in this case) that gives the new generations a selective advantage. They're more likely to survive and reproduce. Survival of the fittest.

Genotype- the genetic makeup of an organism (eg: the recessive gene for black; bb)

Phenotype- physical feature of an organism as determined by the genotype (the colour black)

Selective pressures will increase the number of brown beetles. The correct option is 2.

What is Selective pressure?

Any factor that reduces or increases reproductive success in a subset of a population may exert evolutionary pressure, selective pressure, or selection pressure, thereby driving natural selection.

Selection pressure can be defined as a force that causes an organism to evolve in a specific direction.

It is not a physical force, but rather an interaction between natural variation in a species and environmental factors that causes certain forms to have an advantage over others.

A beetle species can be either black or brown in color. A single gene determines the color of the beetle, and black is recessive to brown.

The soil in the area has darkened and taken on the color of black beetles. Brown beetle populations will increase as a result of selective pressures.

Thus, the correct option is 2.

If the length of the small intestine is ( 6 ) meters and the length of the large intestine ( 1.5 ) meters. what is the ratio of the large intestine to the small intestine

Answers

Answer:

1:4

Explanation:

According to the information provided in this question, the length of the small intestine is 6 meters and the length of the large intestine 1.5 meters. This means that the small intestine is longer than the large intestine.

To find the ratio of large intestine to the small intestine, we divide each length value by the smallest (1.5) i.e.

Large intestine = 1.5 ÷ 1.5 = 1

Small intestine = 6 ÷ 1.5 = 4

The ratio of large to small intestine according to this question is 1:4
