why practical sciences is often left out by teachers ?
Answers
Practical sciences are sometimes left out by teachers due to limited time and resources in educational institutions and may prioritize theoretical knowledge over practical application.
Additionally, practical sciences often require specialized equipment, facilities, or materials, which may not be readily available in schools. Moreover, teachers may feel more comfortable with traditional teaching methods and may lack the training or expertise to effectively integrate practical sciences into their curriculum.
Standardized tests and assessment frameworks that focus on theoretical concepts further discourage the inclusion of practical sciences. However, recognizing the importance of hands-on learning experiences, efforts should be made to bridge this gap and promote the integration of practical sciences into educational settings.

exaplian two situations on a pedigree that would allow you to determine the genotype of an induvudal with the dominant phenotype
Answers
1. If the individual with the dominant phenotype has an affected parent with a recessive phenotype.
2. If the individual with the dominant phenotype has affected offspring with a recessive phenotype.
In a pedigree, two situations can help determine the genotype of an individual with a dominant phenotype.
1. If an individual with the dominant phenotype has offspring with a recessive phenotype, it indicates that the individual must be heterozygous (carrying one dominant and one recessive allele).
This conclusion is drawn because the recessive phenotype can only be expressed when an individual has two copies of the recessive allele.
2. Another situation is when both parents have the dominant phenotype, but they produce offspring with the recessive phenotype.
This scenario suggests that both parents are heterozygous (carrying one dominant and one recessive allele), and the recessive phenotype appears in their offspring due to the inheritance of two recessive alleles.
By analyzing these patterns in the pedigree, we can make inferences about the genotype of individuals exhibiting dominant phenotypes.

A single gene with two alleles control variation in haemoglobin type in sheep. There are three different phenotypes corresponding to genotypes S^AS^A S^AS^B and S^BS^B respectively in a flock of 175 sheep the frequency of allele S^A was found to be 0.6 and frequency of allele S^B WAS found to be 0.4
Answers
Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.
Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Alleles Frequencies
S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4Genotypes
S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygousWe need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).
Genotypic and Phenotypic frequencies
F(S^AS^A) = p² = 0.6² = 0.36
F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48
F(S^BS^B) = q² = 0.4² = 0.16
Number of individuals expressing each phenotype
S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individualsYou can learn more about the Hardy-Weinberg equilibrium at

Use current data from scientific sources, such as published scientific journals and news reports, to describe the components of the treaty or agreement. For example, state the CO2 levels for a particular region and explain what that data means in regard to the treaty/agreement and its success or failure.
Answers
The objective of ensuring "finance flows commensurate with a route towards low greenhouse gas emissions and climate-resilient development" is stated in Article 2.1(c) of the Paris Agreement. This ambition extends much beyond the typical focus of climate financing on assisting impoverished nations.
For example, Ghana's total greenhouse gas emissions in 2019 were 58.56 MtCO2e (million tonnes of carbon dioxide equivalent), 16% more than in 2016. Because of this continued rise in Greenhouse emissions as well as the existence of harmful chemicals in their cocoa, Europe recently indicated that they'd be cutting back on how much import they off-take from Ghana.
What is the Paris Agreement about?The Paris Agreement, often known as the Paris Accords or the Paris Climate Accords, is an international climate change accord. The pact, which was signed in 2015, addresses climate change mitigation, adaptation, and funding.

is a taxon in the modern revised Linnaean system that is larger and more inclusive than the kingdom.
Answers
Answer:
The domain is a taxon in the modern revised Linnaean system that is larger and more inclusive than the kingdom.
Explanation:
The domain is larger and more inclusive than the kingdom in the modern revised Linnaean system because it reflects our current understanding of the diversity of life on Earth. The three domains are Archaea, Bacteria, and Eukarya, and they are based on fundamental differences in the cellular organization and biochemistry of living organisms. The domain is a more inclusive taxonomic category than the kingdom because it groups organisms based on their fundamental similarities at the cellular level, whereas the kingdom is based on observable differences in morphology and physiology.

1. It takes considerable energy for a bacterium to make antibiotics and to release it into its surroundings. What is the evolutionary advantage conferred by the ability to do this? In other words, what do the antibiotic producers get for all their effort?
Answers
Bacteria produce antibiotics to protect themselves from potential competitors and predators in the environment.
The production of antibiotics requires energy and resources, but the bacteria that can produce them also have great advantages.
One of the advantages of producing antibiotics is that they can help bacteria seek out resources in the environment and keep other microbes out.
By producing antibiotics, bacteria can inhibit growth or kill other bacteria that may be competing for the same nutrients or space.
It gives them a competitive advantage and allows them to reproduce within their environment.
In addition to a competitive advantage, the ability to produce antibiotics can also provide protection against predators such as viruses and other parasites.
Overall, antibiotic production can provide bacteria with many evolutionary advantages, such as competitiveness against other microorganisms and protection from predators. This allows bacteria to survive and thrive in the environment.
