<h3>Answer: Scientist can determine if an object should be classified as living or non-living cells by looking under a microscope with a slide. If the slide has cells in it, it is considered alive and if the cells contain food, water, exposed waste, and environment, it is alive. If the object or slide does not have any cells in it, it is considered non-living because for a cell to be alive, it needs cells in it.</h3>

Mary is campaigning for improved air quality in her city. She is very concerned about carbon and methane outputs, but not phosph
Galina-37 [17]

The answer is; D

Carbon dioxide and methane are potent greenhouse gases. They cause heating of the lower atmosphere, by trapping sunlight, that results to climate change. Due to the higher melting and boiling temperatures of phosphorus, it is rare that it occurs as gas in room temperatures. Phosphorus, therefore, does not pose a great threat of climate change.

Feliz [49]

Answer:

1. Ends of the respiratory branches are called alveoli.

2. C. To control blood flow to different areas of the body depending on activities

Explanation:

1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.

The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.  

2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.

This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.

jek_recluse [69]

Answer:

- Protein sequence: Met-Pro-Gly-Lys-Ile-Arg-Arg-Pro-Pro-Gly-Thr-Pro-Leu-Phe-Gly-Lys-*

- DNA 5' UTR: ATTTTAGCC

- RNA 3' UTR: UAAAAAUAAAAU

Explanation:

Transcription is the process in which a DNA sequence (e.g., a gene) is used as template (transcribed) in order to synthesize an RNA molecule, usually a messenger RNA molecule, which is then used as template to produce a polypeptide sequence (protein) in the ribosomes. In RNA, Thymine (T) bases are always replaced by Uracil (U) bases. An mRNA strand is formed in the 5′ to 3′ direction. Each triplet of nucleotides is referred to as a codon and the resulting mRNA strand is translated starting from codon AUG (Methionine), while there are three different stop codons or 'or termination codons' in the genetic code that terminate translation: UAG, UAA, and UGA.

A normal chromosome and its homolog carrying an inversion are given. The dot (•) represents the centromere. Normal: M N • O P Q
AlladinOne [14]

Answer:

Pericentric, inversion loop.

Explanation:

Chromosomal inversion may be defined as the rearrangement of chromosome that may get reversed and attached. Two main types of inversion are pericentric inversion and paracentric inversion.

The pericentric inversion involves the inversion of chromsome and centromere is involved in this inversion. M Q P O • N R S T , in this case centromere is present and shows the pericentric inversion. The structure that forms during the synapsis is known as inversion loop.

Thus, the answer is pericentric, inversion loop.
