7. Based on what you know about Carbon Dioxide (look at the definitions section) and the Description of the Landscapes, how did the amount of Carbon Dioxide in the atmosphere increase over time? 8. Carbon Dioxide and Water vapor are greenhouse gases. How do greenhouse gases act like the glass in greenhouses?
Answer: Carbon dioxide levels today are higher than at any point in at least the past 800,000 years. Global atmospheric carbon dioxide concentrations (CO2) in parts per million (ppm) for the past 800,000 years. ... Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. The large numbers of land animals raised to feed the Earth's growing population results in increased carbon dioxide levels in the atmosphere due to farming practices and respiration and methane production. This is another example of how human activity indirectly affects biogeochemical cycles in a significant way. 8. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse.

It helps to support growth and helps producing energy to do vital functions.
Hope this helps!
A reliable DNA analysis is based on the DNA conditions. The importance of using undigested cells is that DNA is well-preserved, not affected by external factors, and can be used to compare it to database sequences.
------------------------------------------
Dr. Pringle studies niche partitioning and competition reduction among coexistent species in Africa.
He is interested in knowing the exact source of food of different herbivorous species. To do so, he is using the technique of DNA metabarcoding.
He collects fresh animals' dung and gets the indigested plant cells.
DNA is isolated, sequenced, and compared with the DNI of known species, which are a potential source of food for these animals.
Once he matches the cells' DNA with the corresponding plant species from the database, he can use this information to detail the animal's source of food.
The importance of getting fresh, undigested cells from the dung, is that
The animal's digestive enzymes have not broken the cell walls and digested the cell content. The dung environmental conditions such as pH, temperature, or microbiota have not affected the cell's DNA. Undigested cells' DNA is well-preserved and can be used to compare it with the plant species database.------------------------------------------------------

A. produces gametes with half genetic information than parent cell.
B. allows processes as growing and repair tissues in the body.
C. does not produce cells with the same genetic information than parent cell.
D. always produce somatic cells with the same characteristics, it does not matter the organ in the body.
Answer:
B. allows processes as growing and repair tissues in the body.
Explanation:
Mitosis is a process where a single cell divides into two identical daughter cells. During mitosis one cell divides once to form two identical cells and the dividing cell's chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells.
The major purpose of mitosis is for growth and to replace worn out cells. It also plays an important part in the development of embryos.
Mitosis is divided into five stages:
1. Interphase- during interphase, the DNA in the cell is copied resulting in two identical sets of chromosomes. Microtubules also extend from the centrosomes outside the nucleus
2. Prophase- during this phase, the sister chromatids in each chromosome pair up, the nuclear membrane dissolves and the mitotic spindle consisting of microtubules and other proteins extend across the cell between the centrioles which move to opposite ends of the cell.
3. Metaphase- the chromosomes line up at the centre of the cell and the mitotix spindle attaches to eachmof the sister c hromatids.
4. Anaphase- the sister chtomatids are pulled apart to each end of the cell by the mitotic spindle.
5. Telophase- at each pole, a full set of chromosomes gather together, a membrane encloses each chromosome, the cell pinches at the middle and then divides into two. This is known as cytokinesis.

A population of 250 birds inhabit the canopy of tropical rainforest that has a caring capacity of 400 birds. What is the maximum population growth if a population grows 283 in one year
Answer:
Explanation:
0.35
The maximum population growth if the population grows 283 in one year is : 13.2%
Maximum population growth is the percentage change in the size of the population of a habitat in a given year.
Caring capacity = 400 birds
Initial population at the start of the year = 250 birds
Number of birds added = 283 birds
population growth rate = ( 283 - 250 ) / 250 * 100
= 0.132 * 100 = 13.2 %
Hence the maximum population growth rate if the population grows 283 in one year is 13.2%

Which best describes how to classify water?
A It is an element because it is made
from a pure substance.
В
It is a compound because it is made
of a single kind of molecule.
© It is a mixture because it is composed
of more than one molecule.
D It is a solution because it is a
homogenous mixture of different
compounds.
Answer:
D
Explanation:
Water is a compound and scientifically known as H[tex]_{2}[/tex]0 (2 hydrogen atoms and 1 oxygen). Therefore, the answer is...
Not A because water is not an element of one pure substance; rather, it is a compound and can be broken down into two pure substances.Not B because the statement contradicts itself: a compound is made of different atoms and, thus, different molecules.Not C because a mixture contains different substances that are physically -- not chemically -- combined. And as we know, water is a compound, which means that its atoms are chemically bonded to one another. Or else it would just be 2 free hydrogen atoms and 1 oxygen.D (yay!) because it is not the *most* accurate, but simply the best description of those provided. Water can be described as a homogenous (uniform in appearance) mixture because, minus the "mixture" part, that's what it is, essentially: a substance that looks pure but is really made of up different molecules.Ngl this was tricky, but I hope this helps :)
Neuromodulation is the release of chemicals (other than ____________ ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called ____________ . Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is ____________ . This may result from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called ____________ . This results from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons.
Answer:
Neurotransmitters; neuromodulators; facilitation; an increased; an increased; inhibition; a decreased; a decreased.
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Neuromodulation is the release of chemicals (other than neurotransmitters ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called neuromodulators. Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is facilitation. This may result from either an increased amount of neurotransmitter in the synaptic cleft or an increased number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called inhibition. This results from either a decreased amount of neurotransmitter in the synaptic cleft or a decreased number of receptors on postsynaptic neurons.

Answer:
4. Absorb extra fluid between the cells
Explanation:
The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.

During a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. A second student responded that the behavior might frighten predators. Which statement best describes these explanations?
Answer:
The first explanation refers to proximate causation, whereas the second refers to ultimate causation.
Explanation:
The first example refers to proximate causation, whereas the second example to ultimate causation.
What is ultimate causation?The ability of one variable to impact another is known as causality, also known as causality. The first variable might create the second or might change the incidence of the second variable.
Correlation, which shows how much two variables tend to rise or fall together, and causation are frequently misconstrued. Correlation does not, however, automatically imply causality. The variations in both variables could be caused by a third component, for instance.
A statistically significant association has been shown between yellow cars and a reduced accident frequency. Just because there are fewer accidents involving yellow cars does not mean that they are any safer. A third element, such as the person's personality type.

What are cell organelles?Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.
This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.
Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.
