what satellites are used to study expanses of the oceans surface
Answer:
The Geostationary Operational Environmental Satellite-16 (GOES-16) is the first of NOAA's next generation of geostationary weather satellites. Among the many missions of this satellite, it will collect ocean and climate data.
Explanation:
Using satellites, NOAA researchers closely study the ocean. Information gathered by satellites can tell us about ocean bathymetry, sea surface temperature, ocean color, coral reefs, and sea and lake ice. Scientists also use data collection systems on satellites to relay signals from transmitters on the ground to researchers in the field—used in applications such as measuring tidal heights and the migration of whales. Transmitters on satellites also relay position information from emergency beacons to help save lives when people are in distress on boats, airplanes, or in remote areas.

What performs more functions human cells or bacterial cells and why
Answer:
It is human cells
Explanation:
In humans, the dominant allele N causes an abnormal shape of the patella in the knee, whereas n is the recessive normal allele. A separate gene is concerned with finger length, and the dominant allele B causes abnormally short fingers, whereas b is the recessive normal allele. A study focused on people who have both abnormal patellae and short fingers. These individuals were N/n . B/b in genotype, having inherited the N allele from one parent and the B allele from the other parent. These N/n . B/b people mated with normal spouses, producing 40 progeny classified as follows: Normal 3 Abnormal knees and short fingers 2 Abnormal knees only 17 Short fingers only 18
Explain why the four types of children were found in the proportions shown.
Draw the chromosomes of (i) the parents of the N/n . B/b individuals; (ii) the N/n . B/b individuals; and (iii) the four types of children, showing the proper positions of the alleles based on the data above.

One of the favorites to win a marathon to be held at sea level has been invited by a sponsor to train in Bolivia (very high altitude place) for three weeks before the race. The sponsor has promised to fly him to the race a day before the race. Based on your understanding of hemoglobin function, would you advice the athlete to accept the invitation or continue with his/her plans to train at low altitude
Answer: At high altitude the body will get prepared for marathon.
Explanation:
The human body is able to adapt the high altitude by long-term and immediate acclimatization. At high altitude the lack of oxygen is sensed at the carotid arteries. It causes the increase in rate of breathing or hyperpnea.
In addition at high altitude the heart beats faster, gradually the body will also compensate itself for low availability of oxygen and get prepared for marathon.

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
Explanation:
Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.
During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.

A local ecosystem includes a variety of grasses that grow on spongy soil. In spring, heavy rainfall and melted snow cover the soil in a few inches
of water. The ecosystem dries up by late summer. What term BEST describes this ecosystem?
A. pond
B. estuary
C. wetland
D. stream bed
Answer:
The correct answer is C. Wetland.
Explanation:
A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.
Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.

The climate has three main zones such as tropical, temperate, and polar.
What are Earth's climatic zone?
A climate zone refers to a condition by observing different factors like temperature, humidity, precipitation, season and natural vegetation of an area.
Earth's climate zones is surrounded by the horizontal belts of different climates such as tropical, dry, temperate, continental, and polar zones.
Firstly, Tropical climate zones which present near the Equator of earth and have high temperatures and high precipitation, while Dry or arid climate zones shows high temperatures and little annual precipitation.
Similarly temperate climate zone observed Earth’s middle latitudes and shows wider temperature and seasonal variations are more distinct.
Continental climate zone observed in mid-latitudes, shows swing of temperatures from cold in winter to warmer, where as polar climate zones shows harsh climate which cannot to support vegetation.

You remove pus from a wound and try to identify the pathogen multiple ways. The multi-locus gene tree showed your organism was most closely related to Streptococcus pyogenes but the 16S tree said it was most closely related to Streptococcus pneumoniae. Describe why this might be the case and other ways you should try to identify this organism.
Answer:
It occurs because phylogenetic analyses based on the 16S rRNA gene sequences may have insufficient resolution for distinguishing between closely related species
Another genomic method for streptococcal identification is whole-genome analysis (WGS)
Explanation:
The phylogenetic analysis of the highly conserved 16S rRNA gene sequences has recently been used to distinguish between prokaryotic species. However, this gene sometimes may show low resolution to distinguish between closely related species, and it has been suggested potential horizontal transference of rRNA genes. Moreover, multi-locus sequence analysis (MLSA) has also been used to identify species. MLSA analysis consists of analyzing simultaneously different genes and this technique has shown to have a high capacity for establishing relationships between species within a genus or genera within a family. Finally, whole-genome analysis (WGS) is the most powerful tool for distinguishing between closely species. WGS is a technique that provides a very high resolution which is based on the analysis of large-scale genome sequencing data generated by next sequencing generation (NGS) technologies.
