Answer:

Autotroph

Explanation:

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

Answer:

The correct answer is "Yamnaya".

Explanation:

In genetics, a population or genetic bottleneck is defined as a reduction on the size of a population as a result of an environmental effect or human intervention. Regarding the Y chromosome bottleneck, the Yamnaya is an ancient population that contributed the most due to its sex-biased and stratified culture. The Yamnaya were violent and left behind many male skeletons, where just few type of persons were able to reproduce.

The correct option is D, as epidemiological studies showing that individuals with the CFTR mutation have a higher risk of developing respiratory infections and other complications provide support for the idea that the mutated form of the CFTR protein is harmful to humans.

F508del is the most prevalent CFTR mutation, seen in around 70% of patients with CF. The deletion of three base pairs in the CFTR gene results in the lack of an amino acid termed phenylalanine, abbreviated F, in the CFTR protein.

Recessive diseases include cystic fibrosis.

A mutated variant of the CFTR protein is dangerous. Individuals who inherit the mutant variant of the gene are more likely to experience major health issues.

Option D is accurate because it implies that epidemiological research supporting the hypothesis that the mutant version of the CFTR protein is detrimental to humans would demonstrate that people with the CFTR mutation have a higher chance of having respiratory infections and other issues. This is consistent with the widely held belief that the CFTR mutation has detrimental effects on health and causes problems with cystic fibrosis.

6. Observation and respond

An independent variable is a variable that's can't changed in an experiment. An explanation based on an observation is a hypothesis.

Skill observation is made using one or more of the five senses that changed in an experiment. There may be only one independent variable in an experiment. Quantitative observation is made using tools or measurement.

Using one or more of the five senses that changed in an experiment is refer to Skill observation. The difference between an observation and inference is that an observation uses our five senses.

While an inference is a conclusion that we draw based on our observations. A responding variable is a thing that “responds” to changes you make in an experiment. It is the effect or outcome in an experiment.

Explanation:

The kangaroo is the animal that can produce the most genetically diverse gametes. Like the majority of marsupials, kangaroos have numerous sets of sex chromosomes.

A variety of bands techniques were used to study the mitotic and meiotic chromosomes of the semi-aquatic rat Ichthyomys pittieri (Rodentia, Cricetinae) from Venezuela. This unusual species has a diploid chromosomal number of 2n = 92, the greatest value for a mammal.

The eukaryotic species with the most chromosomes per cell is the Atlas blue butterfly (Polyommatus/Plebicula atlanticus), a diploid, non-polyploid species. Each of its 448–452 chromosomes (or 224–26 pairs), which make up one cell, is native to Morocco and Algeria.

Environmental factors-Sunlight,Proper temperature,Moisture ,Air and nutrients.

This effect the growth of plant.When the plant get enough of all these factors,they grow well.Same in the case of more ripe red tomato.

Genetics-When a plant contain that DNA which contains the gene more strongly which can pass from one generation to another more easily,these are called as more strong gene or dominant gene.

So,the ripe plant have more these strong genes,so they are more grown.

Claim-The plant which getting better environmental and genetic factor are grown better.

Evidence-Based on the question and information given,the unripe plant grows lesser as compared to ripe plants.So,we have to find the evidence for these.

Reasoning-The main reason is genetics,is the presence of Strong gene/Dominant gene .

Environmental factor-Which affects a lot the growth of plant,which are explained above.

All of these compose the 98.5% of the human genome that does not encode proteins.

The entire set of genetic instructions that make up an individual is contained in the human genome. It includes all the knowledge required to construct and maintain a human body. The 3 billion nucleotide bases that make up the human genome are what DNA is made of. The 20,000–25,000 genes, or DNA segments that code for proteins, are made up of these nucleotides. Only 1.5% of the human genome, however, actually codes for proteins.

Non-coding DNA or non-coding sections are terms that are frequently used to describe the remaining 98.5% of the human genome. It was originally believed that this non-coding DNA was merely "junk DNA" with no functional use. However, recent studies have revealed that non-coding DNA is crucial for controlling gene expression, chromosomal structure, and other processes.

To draw a Punnett square for Elizabeth and Alan, we need to consider their genotypes for the PKU disease.

Elizabeth is a carrier of PKU, which means she has one normal allele (denoted as N) and one PKU allele (denoted as p). Therefore, her genotype is Np.Alan is homozygous recessive for PKU, meaning he has two PKU alleles (pp) and does not have a normal allele.

The Punnett square will show the possible combinations of alleles that their child, Sarah, could inherit.

 |   N    |   p    |

-----------------------------

  p   |   Np   |   pp   |

-----------------------------

  p   |   Np   |   pp   |

-----------------------------

In the Punnett square, the top row represents the alleles from Elizabeth (Np), and the left column represents the alleles from Alan (pp).

From the Punnett square, we can see that there are two possible genotypes for Sarah: Np and pp.

If Sarah inherits the genotype Np, she will be a carrier like her mother Elizabeth. She will have one normal allele and one PKU allele, but she will not have the disease.If Sarah inherits the genotype pp, she will have PKU since she has received two PKU alleles from both parents.

It's important to note that Punnett squares provide a theoretical representation of genetic outcomes and do not guarantee the actual genetic inheritance of a child.

An adaptation that would be more advantageous to a desert-dwelling organism than to a rainforest-dwelling organism is the ability to conserve water.

In a desert environment, water scarcity is a significant challenge for organisms. Therefore, adaptations that enable efficient water conservation would be highly advantageous.

Desert-dwelling organisms may have features such as specialized kidneys to concentrate urine, reduced sweat glands to minimize water loss through perspiration, or the ability to extract water from the food they consume.

These adaptations help them survive in arid conditions by reducing water loss and maximizing water retention within their bodies.

On the other hand, rainforest-dwelling organisms face a completely different set of challenges. The rainforest is characterized by high humidity and abundant rainfall. As a result, water availability is not a limiting factor for survival.

Organisms in the rainforest may have adaptations that promote efficient heat dissipation, such as larger surface areas for evaporative cooling or increased perspiration.

These adaptations are advantageous in a high-moisture environment where excessive heat and humidity can pose challenges to thermoregulation.

Therefore, the ability to conserve water would be more advantageous to a desert-dwelling organism as compared to a rainforest-dwelling organism, given the contrasting water availability and environmental conditions in these two habitats.
