Answer:

a. They emit more carbon than they take in

Explanation:

The carbon sinks are basically the natural storage for carbon. The oceans and the forests are some of the carbon sinks, and are the two of the biggest. They have the ability to take in more carbon than they emit back into the atmosphere, thus they are actually keeping the greenhouse effect under control and not letting it increase significantly. A perfect example for carbon sinks are the deposits of coal that the humans have been using since the industrial revolution intensively. The coal is made out of the trees that existed in the Carboniferous, hundreds of millions of years ago, and that carbon was stored deep inside the ground for all that time until the humans intervened.

The statement that carbon sinks emit more carbon than they take in is not true. Carbon sinks, like oceans and forests, absorb more carbon than they emit, serving as a significant part of the carbon cycle.

In regards to carbon sinks, statement a: 'They emit more carbon than they take in.' is not true. A carbon sink is an environment that absorbs more carbon than it releases. Examples of carbon sinks are the oceans and forests. They absorb carbon from the atmosphere and store it, thereby regulating carbon in the atmosphere and helping to counteract emissions of carbon dioxide and other greenhouse gases.

Through the process of photosynthesis, forests convert carbon dioxide into organic carbon and release oxygen back into the atmosphere. Oceans, on the other hand, absorb vast quantities of carbon dioxide from the atmosphere and store it, both on the surface and in deep sea sediments.

It's important to note that while carbon sinks can absorb and store carbon, they do not emit more carbon than they absorb, which is a characteristic of carbon sources, not sinks. Carbon sources include volcanic activity and human activities like burning fossil fuels.

B there is 7 electrons

An atom of nitrogen has (B) seven electrons.

In an atom in neutral state, number of electrons are equal to the number of protons. Since nitrogen has an atomic number of 7, which indicates the number of protons in its nucleus, it also has seven electrons to balance the positive charge of the protons and maintain an overall neutral charge.

Electrons are subatomic particles carrying a negative electrical charge. It is one of the fundamental particles that make up atoms, along with the protons as well as the neutrons. Electrons are a part of the family of elementary particles known as leptons. The movement of electrons within materials is responsible for electrical current flow and the generation of electromagnetic fields.

c. both organisms benefit

Explanation:

Answer:

c

Explanation:

Answer

Nasal cavity

Larynx

Pharynx

Trachea

Bronchi

Answer:

Nasal cavity, pharynx, larynx, trachea and bronchi.

Explanation:

Respiration may be defined as the process of the exchange of gases between the external environment, lungs and tissues. Oxygen is inhaled in and carbon dioxide is exhaled out from the body.

The first passage way of oxygen is the nasal cavity. From the nasal cavity, the air is passed to the pharynx. Pharynx is also known as the throat of the body. From the pharynx,  the air is passed to the layrnx. Larynx is the voice box. The air is then passed to the trachea or the wind pipe. From the trachea, the air is passed into the lungs that contains the small branches called bronchi.  From brochi to the alveoli and finally into the body tissues.

Thus, the answer is nasal cavity, pharynx, larynx, trachea and bronchi.

Answer: i believe it is b, they are less likely to mate

Answer:

They are less likely to attract mates and pass on their genes.

Explanation:

The singing of birds uses a lot of energy from their bodies, for this reason, birds that do not eat properly tend to sing less often to save the little energy they have. However, birds only sing when they have motives and the main reason for this song is to attract reproductive partners for mating. With this, we can conclude that if the bird does not eat well, it will have little energy and will not have frequent frequency, so it will be less likely to attract partners and transmit its genes.

Throughout the year, these animals sing more in the spring. This period is the breeding season for birds, who wish to demarcate territory and attract females. In the following season, the summer, the chicks are born, and the singing decreases. In addition to not wanting to attract unwanted visitors to the nest, both the male and the female are totally focused on raising the young.

Answer:

AA , Aa , Aa and aa

Explanation:

AA X aa gives 4 Aa (F1)

When F1 is crossed Aa x Aa gives AA ,

2 Aa and aa (F2 generation)

Each F1 heterozygous parent can pass one of four allele combinations to the F2 generation: YY, Yy, yY, and yy, leading to a 1:2:1 genotypic ratio and a 3:1 dominant to recessive phenotypic ratio.

To understand the combinations of alleles each F1 parent can pass onto their offspring, it's helpful to use a Punnett square for visualization. In a monohybrid cross of a heterozygous (Yy) F1 individual, there are four potential allele combinations for the F2 generation: YY, Yy, yY, and yy. When analyzing the genotypes, it turns out there are two ways to get a heterozygous (Yy) result, which are counted separately. However, since Yy and yY are identical, we combine them, resulting in three genotypes with a ratio of 1:2:1 (YY:Yy:yy).

This ratio supports the observed 3:1 phenotypic ratio seen by Mendel, due to the YY and Yy genotypes both presenting the dominant phenotype (for example, yellow peas), while the yy genotype displays the recessive phenotype (e.g. green peas). Each allele combination happens due to the equal segregation of alleles during gamete formation and the random nature of fertilization. The expected phenotypic ratio, applying the sum of probability, is therefore 3 dominant:1 recessive.

Answer:

an entire desert including abiotic factors

Explanation:

An ecosystem includes all living (biotic) and nonliving (abiotic) factors in an area that interact, therefore an entire desert including abiotic factors can be considered an ecosystem. The living community within a desert, the population of fish in a small lake, and a rotting log are all examples of an ecosystem due to their combined biotic and abiotic components.

Given the options presented in the question, an entire desert including abiotic factors can be considered an ecosystem. This is because the term ecosystem applies to a natural unit consisting of all the living organisms in an area functioning together with the nonliving physical factors of the environment. A community of organisms within a desert or a population of fish in a small lake both represent biotic communities, while the wood of a rotting log can also be classified as an ecosystem due to the interacting species and abiotic factors present.

Answer:

exponential growth, it will exceed the carrying capacity of its environment and then the population will crash down to or below it and continue a boom and bust cycle.

The population which have an exponential growth rate is at high risk for a population crash as the population grows at a very fast rate and reaches the carrying capacity which will lead to decline in the population.

The growth of a populations can be explained by the two main models which explains how the population size changes over time. The models are exponential growth and logistic growth model.

Population growth depends upon the size of a population, with the main factors including fertility rates, mortality rates, initial age profile of the population and migration of species from a population.

The main causes of a population crash include the scarcity of environmental resources which are required for the survival, growth and reproduction of a population, predation, and waste accumulation in the ecosystem. Population crash can also be caused by an initially overpopulated group of species and by the competition between the members of a species.

The immune system functions in conjunction with the circulatory system by having white blood cells travel through blood vessels to areas where they are needed to destroy pathogens. Therefore, the correct option is C.

The immune system and the circulatory system work together intricately to maintain body health. White blood cells (leukocytes), including monocytes and lymphocytes, are a crucial part of the immune system. These cells travel throughout the body via the blood and lymphatic systems as part of the circulatory system to detect and fight pathogens. The correct choice that describes how these two systems collaborate is:

C. White blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to destroy pathogens.

The circulatory system also transports nutrients that are vital for the immune system's proper functioning and aids in removing waste products created by the immune system during the fight against invaders.

Answer:

A. share one common ancestor that isn't also shared by organisms in other groups.

Explanation:

A monophyletic group includes all the descendants of an ancestral species. On the other hand, a paraphyletic group includes some descendants of a common ancestor. Protists are not monophyletic as they share a common ancestor with other groups. Hence, protists are said to be paraphyletic. Mammals are monophyletic as all the mammals share a common ancestor which is not shared by organisms of any other groups.

Answer:

There would be no seasons anywhere on Earth

Explanation:

If the Earth's axis was not tilting and it was at a 90 degrees angle relative to its orbit, then the seasons on Earth would disappear. The climate on the planet would be defined by the latitude. The equator and the areas close to it would always have summer, as they will receive direct sunlight throughout all of the year. The mid-latitudes will always have temperate climate, reminding of spring and autumn, as the sunlight will not be very direct, but it will also not be very dispersed, jut enough to create a constantly pleasant climate. The higher latitudes will always have winter, as the sunlight will come at a very low angle throughout all of the year, thus it will be very dispersed, not enough to ever warm this parts enough, so they will constantly be under ice.

Answer:

The entire planet would experience the same season at any given time.

Explanation:

Due to the tilt, some parts of the earth will be tilted towards the earth at a particular point in the orbit while others will be tilted away from the sun. This means the amount of sunlight reaching these points is differential. This also changes dynamically, more pronounced in the poles, as the earth revolves around the sun. Without the tilt, this phenomenon would not be therefore and there would be no changes as the earth revolves around the sun.
