The law of superposition states that fossils found in the uppermost layers, i.e., layer A, are more recent than those found in the other layers, so option A is correct for the youngest fossil.

When the environment changes due to climatic changes, animals or plants remain under the rocks, leaving their imprints or hard parts of their bodies, which are later studied to learn about ancestors. The fossils that are present in the lowermost rock layers are the oldest, while the uppermost layer is the youngest as it is newly formed.

As a result, the law of superposition states that fossils found in the uppermost layers, i.e., layer A, are more recent than those found in the other layers, so option A is correct for the youngest fossil.

Answer:

The correct answer is 4.2105.

Explanation:

The birth rate is the period of the total number of individuals with live births per 1,000 population divided by the length of the period in years.

Birth rate = (live births/total population)*1000

= 4,000/950,000 x 1,000

= 4.2105

Thus, the correct answer is 4.2105.

Answer:

It will reduce the cost and energy used to treat the water

Explanation:

Water conservation can help control water pollution by reducing the amount of water that needs to be treated and processed. When less water is used, less polluted water is generated from households, industries, and agricultural activities.

Water conservation reduces the amount of wastewater that needs to be treated and discharged into natural water bodies, such as rivers and lakes. Additionally, conservation measures such as using low-flow fixtures, fixing leaks, and reducing water-intensive activities can help reduce the amount of energy needed to treat and transport water, which also reduces the carbon footprint and associated pollution from energy generation. Overall, water conservation is an effective way to reduce the demand for water resources and minimize the pollution that results from water use and treatment.

Hence, water conservation can help control water pollution by reducing the amount of water that needs to be treated and processed. When less water is used, less polluted water is generated from households, industries, and agricultural activities.

The two statements that best describe why chromosomes are important to the function of a cell are:

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibers in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.

Chromosomes play a critical role in organizing and compacting the DNA into a more manageable structure that allows for efficient gene regulation and gene expression. Chromosomes condense DNA into a more compact structure during cell division, which facilitates the proper separation and distribution of genetic material to the daughter cells.

Answer:

genetic

Explanation:

DNA is a form of genetic material. DNA contains the necessary instructions for growth and development.

Living organisms have genetic material which codes for its growth and development.

Thus, Every living creature shares a few traits. The instructions for inheritance are encoded in the genetic code, and children typically resemble their parents.

Asexual reproduction produces children that share the characteristics of their parents. Offspring from sexual reproduction are sometimes different from their parents.

Energy and resources are used by living things to expand, change, and procreate. A group of chemical processes known as metabolic reactions are involved in these life activities.

Organisms have the ability to recognize changes in their surroundings and react to these stimuli. Most living things need their internal surroundings to stay within a pretty narrow range in order to sustain equilibrium.

In order to comprehend marine organisms, marine biologists study biological oceanography as well as the related fields of chemical, physical, and geological oceanography.

The scientific study of marine life, or marine organisms, is known as marine biology. Marine biology uses the environment rather than taxonomy to classify species because many phyla, families, and genera have species that live in the sea and others on land.

Marine biologists' primary focus is on research projects that involve collecting specimens at sea, compiling data, and carrying out laboratory-based experiments. Migration patterns, underwater photosynthesis, and the effect of human activity on coral reefs are important areas of study.

This is a feeding network or food chain, it shows producers and top predators, it is expected to find bigger populations for base organisms (producers), meanwhile, for apex predators, we would expect less. This difference in populations numbers has a quite simple explanation, the producers are autotrophs, that is to say, they produce their own food and represent the major energy intake of the system, which is why they must be large populations capable of sustaining the rest of the organisms. In the case of a top predator, are called that way because they don´t have any predator, and in turn, they exert control in the population numbers of downstream organisms, so their populations must be small or they would end the whole chain.

Taking into consideration this information we have three apex predators in this net, bobcat, alligator, and anhinga, These organisms as top predators would be expected to have smaller populations.

Answer:

Syphilis is a sexually transmitted disease

Explanation:

Syphilis is a sexually transmitted infection caused by Treponema pallidum, a spirochaete gram-negative bacterium with various subspecies. This disease is transmitted through direct contact (person to person) by different types of sexual acts. A chancre is an infectious genital lesion that is considered to be the first stage (and symptom) of syphilis. The incubation period of syphilis is 14-21 days. Syphilis can be divided into four stages: primary, secondary, latent, and tertiary. Primary syphilis produces chancres on the genitals, mouth, rectum, etc. Secondary syphilis causes rashes that occur from 2-8 weeks after the chancres. The third (latent) stage is a latent/hidden phase without noticeable symptoms. Finally, the tertiary (late) stage causes large sores within the body that affects the heart, nervous system, etc. The best manner to prevent syphilis is by practicing safe sex (e.g., by using condoms). It has been suggested that syphilis has an estimated transmission rate of 0.5–1.4% per sexual act. Syphilis doesn't have an effective treatment, but this disease can be cured in its early stages with one dose of benzathine penicillin G (administered intramuscularly).

Humans have two sets of homologous chromosomes, so humans are usually diploids, but some organisms can have three or more sets of homologous chromosomes, and that is what we call polyploidy.

Polyploid commonly happens due to abnormal cell division, where the chromosomes fail to separate, or it can be caused by chemical substances.

Polyploid is very common in plants, while most animals are diploids and produce haploid gametes. This is because plants have a different life cycle, and also because self-fertilization commonly happens.

In plants, polyploid is responsible for a good percentage of the speciation events, where the new species has a higher ploidy than the original ones. The fact that there are more copies of certain genes can give adaptive advantages, which promotes rapid speciation.

Most of the polyploid species are the result of sexual reproduction, with an even number of chromosomes, however, there are some triploid species that can only reproduce asexually.

This means C, it can happen fast would be the right option.

Calvin cycle: it is a process by which plants turn the carbon dioxide present in the air into sugar, it is a part of the photosynthesis process.

The Calvin cycle has 3 stages:

1. Fixation

2. Reduction

3. Regeneration

1. Fixation: in this stage the carbon dioxide present in the air enters the chloroplast and reacts with a molecule called ribulose bisphosphate (RuBP). The enzyme RuBisCO helps to catalyze this reaction.

After the reaction 2 three-carbon compounds (called 3-PGA) are formed.

2. Reduction: in this stage the 3-PGA molecules are transformed into glyceraldehyde 3-phosphate (G3P), by using the energy stored in ATP and NADPH.

3. Regeneration: in this stage one of the G3P leaves the cycle to be used in the formation of carbohydrate molecules like glucose (C6H12O6). The remaining G3P molecules are used to regenerate RuBP to be used again in the next Calvin cycle.

Food grains are stored in the warehouse or granary for future use to maintain the production and supply of food in the country and it is also considered as a security measure for the farmers and government agencies.

The grain storage system is important to preserve the nutritional value of the food grains and avoid the losses incurred due to pests, rodents, and other natural calamities such as floods and droughts.

Food grains are the essential components of the human diet, and they need to be stored with utmost care and caution. The quality of food grains plays a crucial role in ensuring the food security of the country. The farmers and the government agencies take care of storing the food grains in the warehouses, which are usually built in the proximity of the grain-producing areas. These warehouses should be equipped with the latest technologies and tools to ensure the safe storage of food grains.

The government also provides subsidies and financial support to the farmers to build their warehouses to store the food grains. The food grain storage system is crucial for ensuring the continuous supply of food and for the survival of the farmers, especially in the developing countries.
