What is climate change?Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle.
Due to global warming many species become vulnerable to climate change. One such species is polar bear. Polar bears live in arctic region and this region is getting warmer due to climate change. Warming of arctic region results into melting of sea ice.
Existence of sea ice is important for the survival of polar bears because seals are the main food of the polar bear and they hunt seals on the sea ice. Therefore, without sea ice, polar bears cannot hunt enough seals to eat thus, it will be difficult for them to survive.

How can gene flow, genetic drift, and natural selection all influence macroevolution?
Answer:
Macroevolution refers to large-scale evolutionary changes that break the species barrier and can give rise to new species and even affect higher taxonomic groups.The basic evolutionary mechanisms migration, genetic drift and natural selection can produce important evolutionary changes if given enough time.Large groups and macroevolutionary trends originate in gradual, adaptive stages, as a product of natural selection acting at the level of individuals , but operating for much longer periods of time.All depends on the mutations originating new alleles or genes, which imply the existence of very different characters from the pre-existing ones, and that these different characters are selected because they imply a better adaptation to the environment.
Explanation:
Macroevolution refers to the evolutionary changes that occur on a large scale, such as the genesis of high-ranking taxonomic groups: the appearance of species within their taxonomic groups, the appearance of evolutionary trends, the acquisition of anatomical characteristics that characterize the groups.For there to be an evolutionary change, then, new properties must emerge that constitute a new species. Evolution is a process of changes at the species level, distinct from those that occur in each individual organism. Gene flow is the transfer of alleles of genes from one population to another. Contributes to variation and diversity of individuals. Evolution is then the change of allelic frequencies over time.Macroevolution takes place through the process of natural selection, that is, the differential reproduction of individuals, and adaptive improvement over a very long period of time. This type of evolution is based on interpreting the appearance of new species or large groups, as well as mass extinctions, with the subsequent proliferation of new groups. The evolutionary changes that determine the origin of body plans are based on macromutations on which natural selection acts.

The given question is incomplete as it lacks the options required to answer the question, however, options for the question is as follows:
A. Photosynthesis
B. Cellular respiration
C. both A and B
d. None of the above
Answer:
The correct answer is - option A. cellular respiration.
Explanation:
Plants produce their food or glucose with the help of the photosynthesis process. Plants called autotrophs as they generate their food on their own whereas animals depend on plants and other animals for their food and energy.
Plants and animals both perform cellular respiration in order to convert the food or glucose to the useable energy form that is known as ATP. Cellular respiration converts glucose into energy and releases carbondioxide and water.
The animals have the process of the Cellular respiration, to produce energy from the food they eat.
Cellular Respiration:
It is the process by which all organism perform to generate energy as ATP from the Glucose and produce Carbon dioxide as by product.

What is brine rejection?
Answer:
hope this is right.
Brine rejection is a process that occurs when salty water freezes. The salts do not fit in crystal structure of water ice, so that salt expelled. Since the oceans are, this process is important in nature. In better understanding, as salt water freezes, the salt is pushed out of solution through channels in the ice. This process is called brine rejection or brine exclusion.

1. Why is California at hingher for earthquakes than North Dakota
Answer:
because California is located on the San Andreas Fault
Explanation:
California is one of the states that have higher seismic activity because it lies on an individual fault known as the San Andreas Fault. Faults are regions where two tectonic plates are moving with respect to one another, thereby they are prone to suffer earthquakes. The San Andreas Fault is a continental fault that extends approximately 800 miles (1,200 kilometers) through the US state. Conversely, earthquakes in North Dakota are uncommon because this state is located in the middle of a tectonic plate. The last earthquake in North Dakota had a magnitude of 3.3 (Richter Scale) and it happened almost 10 years ago (2012), in Williston.

(b) Explain how the addition of a phosphate group to certain amino acids of Brec likely affects the tertiary structure and function of Brec. Explain how
the addition of a small RNA could prevent the activation of kinase D?
Answer:
Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway
Explanation:
Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
1. Adding the phosphate group to the amino acid chains is known as phosphorylation. This attachment affects the tertiary arrangement and function of Brec.
Amino acids join together to form the protein that needs to be stimulated and deactivated for proper functioning.Protein phosphorylation is very crucial in post-translation modification.For protein function, it acts as an activator, inhibitor, reversibly on and offs the switch.Phosphorylation assures a reversible process to the cell to transmit signals for the cell functioning.Therefore, Brec activity can be controlled by the phosphorylation of proteins.2. Small RNA's are RNA fragments which is around 150 nucleotide in length.
Functionally significant small RNA's such as siRNAs, microRNAs scaRNAs and many other acts as regulatory molecules which target and adheres to the mRNA transcripts.This binding inhibits the translation process or degrades the mRNA by activating the RNA interference (RNAi) pathway.RNAi pathway is used to suppress the activation of the kinase D.To learn more about phosphorylation and small RNA follow the given link below:

Answer:
geyser
Explanation:
Local factors are important for regulating blood flow to tissue capillary beds. For example, in skeletal muscle tissue that is actively contracting, levels of oxygen start to decrease as the oxygen is utilized, and levels of carbon dioxide increase as it is produced during cellular respiration. Decreasing levels of oxygen in the tissue cause the smooth muscle forming sphincters in arterioles to relax.
Answer:
true
Explanation:
In smooth muscle contraction, the sphincters relax in the face of the drop in partial tissue pressure of oxygen, and the increase in protons or positively charged hydrogen molecules. In this way, when the sphincter relaxes, the easier and faster contraction of an autonomous and simultaneous nature is conducted.

SlothTickCoral snake Brown-throated sloths (Bradypus variegatus) are tree-dwelling mammals and one of the least active animals on earth. Sloths spend most of their time sleeping or eating young leaves from the trees they live in. The interaction between the sloths and the leaves they eat is an example of a relationship. In this example, sloths are that acquire their nutrients and energy from the they eat. The colors of coral snakes provide these animals with to avoid predation. Specifically, their coloration helps them . The interaction between the hosts and the ticks that live on them can be characterized as , because .
Answer:
The interaction between the sloths and the leaves they eat is an example of a predator-prey relationship. In this example, sloths are herbivores that acquire their nutrients and energy from the plants they eat. The colors of coral snakes provide these animals with mimicry to avoid predation. Specifically, their coloration helps them advertise their toxicity. The interaction between the hosts and the ticks that live on them can be characterized as parasitism, because one species feeds on the other.
Explanation:
Predator-prey relationships are those in which a specie feeds on another specie. The sloth is the predator that feeds on the leaves which are its prey. Herbivores feed on plants. Therefore, the sloth are rightly classified as herbivores.
Coral snakes are brightly colored with red, yellow, and black patches that warn potential predators of their toxicity. Ticks living on hosts are parasitic because the ticks feed on their host.

Explanation:
Scientists believe that there are three jeans what contribute to skin color in humans.
Which of these best describes the inheritance pattern of skin color?
A. Multiple allele in which offspring recessive three allele from each parent.
B. Multiple allele in which offspring recessive three allele from only one parent.
C. Polygenic in which offspring recessive three allele from each parent.
D. Polygenic in which offspring recessive three allele from only one parent.
Answer:
C. Polygenic in which offspring receive three allele from each parent.
Explanation:
In genetics, a polygenic inheritance is an inheritance that involves more than one gene i.e. more than one gene controls a particular trait. This is the case of the skin color trait in humans, which is controlled by three genes.
However, since each gene contains two alleles, each parent will contribute three alleles for the three genes to the development of an offspring i.e. three alleles from the father and three from the mother will result in three genes in the offspring, each containing two alleles.
Answer:D
