Pedigree D is most likely X-linked dominant. What is/are the genotype(s) of the parent(s) that transmitted the mutant allele(s) to their offspring
Answer and Explanation:
Note: In the attached file you will find the pedigree and the genotypes of each member.
Parentals) XDXd x XdY
The female is heterozygous for the trait, transmitting the mutant allele The male is not affected.According to the pedigree, they had the following progeny:
XdXd healthy femaleXdY healthy maleXDXd affected female (this individual transmitted the mutant allele)XDY affected male (this individual transmitted the mutant allele)-Both healthy individuals mated with another two healthy individuals. Their whole progeny was healthy.
-The affected female (XDXd) mated with a healthy male (XdY), and they produced 100% healthy individuals
-The affected male (XDY) mated with a healthy female (XdXd) and they had three affected females, XDXd.

true or false all cells living or dead can produce new living cells
Answer:
TRUE!
Scientist use dead cell embryos to produce living cells
All cells living or dead cannot produce new living cells. Only the living cells can produce new cells. Therefore, the given statement is false.
What is Cell division?Cell division is the process by which a parent cell divides into two new daughter cells. Cell division usually occurs as a part of a larger cell cycle in which the living cell grows and replicates its chromosome before undergoing division.
Cell division occurs in living cells through mitosis and meiosis. The cell division occurs through karyokinesis and cytokinesis. Cell division is a part of the cell cycle. Cell cycle is divided into different phases such as G1 phase, S phase, G2 phase, and M phase.

Phosphatidate (phosphatidic acid) is a precursor in the synthesis of some lipids. Phosphatidate (phosphatidic acid) is a branched molecule. The core of the molecule is a three carbon chain. Carbon one is single bonded to two hydrogens, and a side chain. The side chain is oxygen single bonded to carbon. The carbon is double bonded to oxygen and an R 1 side chain. Carbon two of the core chain is single bonded 1 hydrogen and to oxygen which is single bonded to carbon. The carbon is double bonded to oxygen and single bonded to an R 2 side chain. Carbon three is single bonded to two hydrogens and a phosphate group. P O 4 2 minus. Phosphatidate (phosphatidic acid) Identify the lipids that have phosphatidate as a precursor.
Answer:
glycerolphospholipids, triacylglycerol, and cardoilpin.
Explanation:
PS: Kindly check the attached picture for the structure of Phosphatidate (phosphatidic acid).
The chemical compound known as Phosphatidate or the phosphatidic acid belongs to a group known as phospholipids. Phosphatidate or the phosphatidic acid can be prepared by using the chemical compound known as diacylglycerol kinase to phosphorylate diacylglycerol. Also, Phosphatidate (phosphatidic acid) can be prepared by making use of lysoPA-acyltransferase to acrylate lysophosphatidic acid[a phoshopipid derivative].
The lipids that have Phosphatidate (phosphatidic acid) as precursor are glycerolphospholipids, triacylglycerol, cardoilpin, phosphatidylinositol

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.

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.

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.
Hence, major zones are tropical, temperate, and polar.
