Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories
Answer:
D. 367
Explanation:
If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.
What is food energy?Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.
The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
To find the total calories, multiply the given biomolecules grams with their calorie count.
= 42 × 4 + 7 × 9 + 34 × 4
= 168 + 63 + 136
= 367 calories
Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

What is the difference between a missense mutation and a silent mutation?
Danke schon! Ilysm <3
Answer:
Answer is in explanation
Explanation:
A silent mutation is a mutation in which a single nucleotide base is changed, but that change does not effect the amino acid sequence. A missense mutation is a point mutation in which a single nucleotide is changed, resulting in a codon that codes for a different amino acid.
The mutation is caused by the exchange of one base pair if no change in the overall protein (silence mutation), if there is change in one amino acid (missense mutation).
What is a silent mutation?A mutation is a difference in the DNA sequence of an organism.
Silent mutations happen when the difference of a single DNA nucleotide within a protein-coding portion of a gene does not influence the sequence of amino acids and the protein.
Thus, silent mutation has no change whereas stop mutation leads to termination of protein.

Tropical rainforests have the greatest biodiversity of any type of land ecosystem how does biodiversity contribute to the sustainability of an ecosystem
Biodiversity contributes to the sustainability of an ecosystem in ways such as biodiversity, ecosystem stability, ecosystem resilience, nutrient cycling, pollination, and medicinal properties.
Biodiversity is crucial for the sustainability of an ecosystem as it plays a significant role in maintaining the functioning of ecosystems and providing a range of ecological services. In tropical rainforests, which have the highest biodiversity, the presence of numerous species of plants, animals, fungi, and microorganisms contributes to the sustainability of the ecosystem in the following ways:
Ecosystem Stability: Biodiversity helps to maintain the stability of an ecosystem by providing a balance between predator and prey populations, nutrient cycling, and decomposition.
Ecosystem Resilience: The greater the biodiversity of an ecosystem, the more resilient it is to disturbances such as climate change, natural disasters, and human activities.
Nutrient Cycling: Biodiversity helps in the efficient cycling of nutrients in the ecosystem. Different species of plants and microorganisms play a role in decomposing organic matter, recycling nutrients, and maintaining soil fertility.
In summary, biodiversity is essential for the sustainability of ecosystems. It provides ecological services that are critical for maintaining the functioning of the ecosystem and contributing to human well-being.

Which section of the article BEST explains why the development of CRISPR-Cas9 is significant for the scientific community?
Answer:
It allows the scientists to activate gene expression instead of cutting the DNA.
Explanation:
The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.

State one way by which Carbon Dioxide increases in the atmosphere
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
Answer:
pollution is the way by which carbon dioxide increases

What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

Which process of genetic recombination involves genes from both parents?
crossing over
independent assortment
fertilization
tetrad formation
Answer:fertilization
Explanation:
The process of genetic recombination which involves genes from both parents is crossing over. This process occurs during prophase I of meiosis, when homologous chromosomes pair up and exchange genetic material.
Explain the process?A portion of each parent's chromosome is swapped during this process, resulting in two new chromosomal combinations that are distinct from those of either parent. Genetic variety among the progeny is produced as a result of this process, which is advantageous for evolution.
The process of crossing over is random, therefore it is unpredictable which chromosomal segments will be exchanged. This is crucial for fostering genetic diversity because it allows for a wider variety of genetic combinations to be produced when genetic material is exchanged.
As portions of each chromosome will be exchanged during crossing over, this procedure also aids in ensuring that the offspring obtain a combination of genetic material from both parents.
