Answer:

Ectotherms control their body temperature by relying on coverage of fur or feathers, which act as insulation. ... Brown fat has capillaries that transport heat throughout the body to warm it Brown fat cells have less cytoplasm, which prevents heat loss from the body.

Answer:

The answer is B.

Explanation:

Depending on what order the nitrogen bases are used in the DNA will determine the opposite bases placed on the RNA making the sequence different, making the protein different.

The nitrogenous bases in DNA has the greatest effect on the protein molecule produced by a ribosome. Thus, option B is correct.

Nitrogenous bases in mRNA are the sequence of amino acids. The translation is one of the two-stage events in protein synthesis. Protein synthesis is the process in which protein or polypeptide chains are synthesized by the DNA. This is the use of nitrogenous bases in mRNA.

The process of translation is similar to a smartphone app converts spoken English into Spanish as it involves the translation of the sequence of nitrogenous bases in mRNA molecules to the polypeptide or sequence of the amino acids.

Protein has been defined as the large macromolecules and biomolecules that are made up of long chains of amino acid. There has various function of protein such as DNA replication, speeding up chemical reaction, and helps to maintain the structure of cell.

Therefore, The nitrogenous bases in DNA has the greatest effect on the protein molecule produced by a ribosome. Thus, option B is correct.

Answer:

The first thanksgiving lasted for three days

Explanation:

There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.

Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.

Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).

The week of 40 hours can be converted into minutes by:

Number of minutes in 1 hour = 60

Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes

Therefore, the correct option is B.

Answer:

The two body systems that control homeostasis are the nervous system and the circulatory system.

Explanation:

The nervous system controls everything you do, including voluntary and involuntary actions, and the circulatory system transports important nutrients to your cells to maintain a stable inner environment.

The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.

Answer:

Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.

Motor output that is gotten from the spinal cord to skeletal muscles involves somatic motor neurons of the anterior gray horn. Many somatic motor neurons are regulated by the brain. Axons from higher brain centers form motor tracts that descend from the brain into white matter of spinal cord and then synapse with somatic motor neurons either directly or indirectly by first synapsing with interneurons that in turn synapse with somatic motor neurons.

Sensory receptors is known to detect sensory stimulus.

Sensory neurons often convey sensory input by nerve impulses through their axons. Their axon often start from sensory receptors into the spinal nerve and into posterior root.

From posterior root, axons of sensory neurons have 3 different choices of paths.

Axons that is gotten from spinal cord often synapse with other motor neurons in PNS.

We may consider bees good because they pollinate the plants that give us food crops. We may consider mosquitos bad because they can transmit malaria.

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

We can say that the top of the gel, where the DNA samples were applied, is the negative side, while the bottom of the gel is the positive side.

We can arrive at this answer because:

The correct word to fill the gap would be indirect.

In other words, an indirect survey makes use of evidence, such as the footprints left behind by animals, to follow animals that are difficult to track.

Ecological surveys are of 2 types:

Direct ecological surveys have to do with studying phenomena directly and recording whatever that is observed.

Indirect surveys involve an indirect way of studying phenomena. The signs left by phenomena are observed and logically used to make deductions about such phenomena.

A drug that affects both divisions of the autonomic system is going to bind to, or block the nicotinic neurotransmitter receptor

A chemical that the body produces to interact with those receptors is called an endogenous chemical, whereas a chemical introduced to the system from outside is an exogenous chemical.

Nicotine is not a drug that is used therapeutically, except for smoking cessation. When it is introduced into the body via products, it has broad effects on the autonomic system.

The nicotinic receptor is found on all autonomic ganglia.

Answer:

increases body temperature

Explanation:

this is because when you shiver your blood vessels contract which then increases your body temperature  

If the environment gets cold, humans will often respond involuntarily by shivering in order to increase body temperature. So, the correct option is B.

An environment may be defined as anything that is present in the surroundings of living entities that is either biotic or abiotic.

The process of shivering causes the blood vessels to contract and relax at a rapid rate to maintain homeostasis. The signals of rapid contractions are sent by the hypothalamus through nerve impulses.

Therefore, the correct option for this question is B.
