How did the results of Gerya's model provide evidence for what formed the novae on Venus?

Answer:

Role of organisms in the nitrogen cycle:

Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.

Explanation:

I THINK THIS IS SHORT AND EASY

Plants use nitrates to create proteins. Animals eat plants for protein. Humans add nitrogen-rich fertilizers and manure to the cycle.

The process by which nitrogen is changed into a variety of different chemical forms as it cycles through different ecosystems, including the atmosphere, land, and ocean, is known as the nitrogen cycle, which is a biogeochemical cycle. Both biological and physical methods can be used to complete the transformation of nitrogen.

In order to synthesize proteins, plants must first take up nitrates from the surrounding soil. Plant material is digested by animals, which then contributes to the formation of animal protein. Both the addition of nitrogen-rich fertilizers to the soil and the utilization of manure are examples of how humans make a contribution to the cycle.

The correct option is D. All cells come from pre existing cells.

Answer: we know that the same temperature was named 0°C and 32°F. We write it 0°C = 32°F, and read it: "A temperature of zero degrees Celsius is the same as a temperature of 32 degrees Fahrenheit." Similarly, 0°F = 160/9°C. ... 23°C is 23°C above 0°C. But 23°C = 23*1.8°F and 0°C = 32°F.

Explanation: Mark me brainly please

Answer:

They are the same

Explanation:

(0°C × 9/5) + 32 = 32°F

To convert temperatures in degrees Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.

The heart is a four-chambered organ that is located in the center of the chest. The two upper chambers of the heart are called the atria, and the two lower chambers are called the ventricles. The atria receive blood from the body, and the ventricles pump blood to the lungs and the rest of the body.

The heart is a vital organ that is essential for life. It is responsible for pumping blood throughout the body, which delivers oxygen and nutrients to the cells and removes waste products. The heart is a strong and resilient organ, but it can be damaged by disease or injury. If the heart is not functioning properly, it can lead to a number of health problems, including heart failure, stroke, and heart attack.

In a neuron, the (1) nucleus is found inside the (2) cell body.

The cell body of a neuron, also known as the soma, contains the nucleus. It is the main part of the neuron where essential cellular functions occur, including protein synthesis and energy production.

The nucleus, which is enclosed by a membrane called the nuclear envelope, contains the genetic material of the neuron in the form of DNA. It plays a vital role in regulating the activities of the neuron and controlling the synthesis of proteins needed for various cellular processes.

The cell body serves as the control center of the neuron, integrating incoming signals from dendrites and initiating the transmission of signals along the axon.

It contains various organelles, such as mitochondria for energy production, ribosomes for protein synthesis, and the endoplasmic reticulum for the synthesis and transport of proteins.

The nucleus, as the site of DNA storage and transcription, is crucial for maintaining the genetic information necessary for the neuron's structure and function. Overall, the nucleus within the cell body plays a critical role in coordinating the activities of the neuron and supporting its overall functioning within the nervous system.

To move charges, there needs to be a motive or a driving force that facilitates the flow of electric charges through a conductor. This motive can be provided by various factors and mechanisms.

One of the primary motives for the movement of charges is the presence of an electric field. An electric field exerts a force on charged particles, causing them to move in a particular direction. This force can be generated by applying a voltage difference across a conductor, creating an electric potential difference. The charges will naturally move from an area of higher potential to an area of lower potential, driven by the electric field.

In addition to electric fields, other motives for charge movement can include electromagnetic induction, where a changing magnetic field induces a current in a conductor, and chemical reactions, such as in batteries or fuel cells, where the conversion of chemical energy into electrical energy creates a motive for charge flow.

Ultimately, the motive for moving charges is provided by the presence of a force or potential difference that can overcome any resistances or obstacles in the conductor, allowing the charges to move and establish an electric current.

F is photosynthesis

Matter is conserved in this process because the process can be shown by a chemical reaction equation

This process is a recycling of carbon because it involves the extraction of carbon from the atmosphere into the biosphere.

It is through photosynthesis that matter is conserved. Plants and certain other creatures use photosynthesis to transform atmospheric carbon dioxide  into glucose and other organic molecules. In this process, sunlight's energy is absorbed, and as a consequence, oxygen is released.

The conservation of matter is the idea that during chemical interactions, matter is only altered or reorganized, not created or destroyed.

The ABO allele inheritance patterns and the codominant expression of the A and B alleles lead to the conclusion that AB, A, and B are the possible blood types that can be expressed in their progeny.

Because there are two additional genotypes and matching phenotypes for their progeny, the answer is not AB.

The ABO gene, which has the A, B, and O alleles, governs the ABO blood group system. Two alleles, one from each parent, are inherited by each individual.

The mother here has blood type AB, meaning she carries one A allele and one B allele. The father has two A alleles, which makes him a blood group A. The following allele combinations could occur in their offspring:

AA (inherited A allele from both parents)

AB (inherited A allele from the father and B allele from the mother)

A0 (inherited A allele from the father and 0 allele from the mother)

A person's genotype and the expression of their alleles determine their phenotype. The A and B alleles are codominant in the ABO system, which implies that both alleles are expressed in the phenotype when they are both present.

Consequently, the following phenotypes of their progeny are concei

Blood group A (if the child inherits two A alleles or one A allele and one 0 allele)

Blood group AB (if the child inherits one A allele and one B allele)

Blood group B (if the child inherits two B alleles or one B allele and one 0 allele)

The ABO allele inheritance patterns and the codominant expression of the A and B alleles lead to the conclusion that AB, A, and B are the possible blood types that can be expressed in their progeny. Because there are two additional genotypes and matching phenotypes for their progeny, the answer is not AB.
