Answer:
A
Explanation:
the father doesn't have the trait and since it's recessive, there's no way the baby could have it even if the mother carries it from the grandfather.
There is a 25% chance that the new baby girl will be colorblind. Therefore, the correct option is C.
What is colorblindness?Color blindness is an X-linked recessive trait. This means that the gene responsible for color blindness is located on the X chromosome, and the trait is expressed only when there are two copies of the gene, one on each X chromosome, in females. Males have only one X chromosome, so they will express the trait if they inherit the colorblind gene.
In Emily's family, her maternal grandfather is colorblind. This means that Emily's mother is a carrier of the colorblind gene, since she does not have the trait herself. Emily's father must have two normal copies of the gene, since he does not have color blindness.
When Emily's mother and father have a child, there are four possible combinations of their genes that the child could inherit:
Normal X from mother, Normal X from father (25% chance)
Normal X from mother, Colorblind X from father (25% chance)
Colorblind X from mother, Normal X from father (25% chance)
Colorblind X from mother, Colorblind X from father (25% chance)
Only the last combination would result in a colorblind female, since she would have two copies of the colorblind gene. Therefore, the chance that the new baby girl will be colorblind is 25%.

Monosaccharides are the monomer of which organic
compound?
Monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).
WHAT ARE MONOSACCHARIDES:
Monosaccharides are simple compounds that contain one unit of sugar (saccharide). They are monomeric units of larger organic compounds called POLYSACCHARIDES, which are complex carbohydrates. Monosaccharides cannot be further broken down as they are the simplest form of carbohydrate molecules. Examples of monosaccharides, also called simple sugars are glucose, fructose, galactose etc. and they are monomers of polysaccharide molecules like starch, cellulose etc.Hence, monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).

African elephants once existed in large populations across the African continent. Elephants use their tusks to dig for water and food. Humans hunt and kill elephants for their tusks. Habitat loss and fragmentation have also reduced the total number of elephants and the size of elephant herds. Scientists estimate that the number of African elephants has decreased from several million to several hundred thousand. Population sizes range from over 100,000 individuals in Botswana to approximately 100 individuals in northern Cameroon. Scientists have also found that the frequency of elephants that never develop tusks is increasing.
Select all the statements that describe probable effects of poaching and habitat fragmentation on clephant evolution
a. The elephant population in Botswana will experience high levels of genetic drift.
b. The poaching of elephants for their tusks is leading to the evolution of tuskless elephants.
c. Having tusks does not provide a selective advantage to African elephants.
d. Habitat fragmentation leads to decreases in population size and increases in genetic drift.
e. The elephant population in Cameroon will experience high levels of genetic drift.
Answer:
Option D
Explanation:
In habitat fragmentation, a large ecosystem or habitat of any species is converted into small ecosystems in such a way that each small ecosystem remains isolated from each other. Being isolated , random genetic drift comes in picture and reduces the gene flow with in the isolated habitats.
Hence, option D is correct
What must be true about the number of chromosomes in each sex cell (when compared to the number of chromosomes in body cells
Answer:
The number of chromosomes in sex cell must be haploid (1n) as compared to body cell which is diploid(2n).
Explanation:
Body cells are diploid while the sex cells are haploid. We can say that sex cells contain half number of chromosomes as compared to body cells.
The number of chromosomes in each s-ex cell is half the number chromosomes in body cells.
Chromosomes:Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23. Of the 23 pairs, 22 are known as autosomes. The 23rd pair is made up of the s-ex- chromosomes, called the ‘X’ and ‘Y’ chromosome. These 46 chromosomes carry the g-enetic information that’s passed from parent to child through heredity.

The environmental factors that are important depend on the habitat true or false
Answer:
True
Explanation:
Answer:
true
Explanation:
The statement "carrying capacity can vary depending on environmental conditions" is true. Carry capacity is defined as the maximum population size of a species that an environment can sustain indefinitely. It is also defined as the environment's maximal load of a species. Factors that impact on the carrying capacity of a species are the availability of food and water, raw materials to build shelter, the environment's ability to process waste products, as well as the species' ability to reproduce.

3. d. neither
4. b. gluconeogenesis
5. a. glycolysis
6. c. both
7. a. glycolysis
8. d. neither
Explanation:
Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.
Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.
Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.
Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.
Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.
Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.
Which of the following flows through ecosystems in one direction?
A.water
B.energy
C.carbon
D.nitrogen
Answer:
B energy
Explanation:
because I just know D.
The energy flows through ecosystems in one direction. so the correct option is B. Firstly the energy flows from the sun to autotrophs, or producers. Then it further flows from producers to consumers. Energy never flows backward from consumers to producers.
What is ecosystem?An ecosystem is refers to as a geographic area in which plants, animals, and other organisms, as well as weather and landscapes, work closely to form a bubble of life.
On average only about 10% of energy stored as biomass in a trophic level and is passed from one level to the next. This is called as the 10 percent rule and it limits the number of trophic levels an ecosystem can support.

How does a flash flood compare to flooding?
Answer:
Flood: An overflow of water onto normally dry land. ... Ponding of water at or near the point where the rain fell. Flooding is a longer term event than flash flooding: it may last days or weeks. Flash flood: A flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours.
Explanation:
Answer:
They both cause floods and fill up some places and they are both sometimes caused by rains or broken dams for a pretty long time. Flood is caused by rain and bad weather while flash flood is the result of water overflowing from a contained location like a lake, river or reservoirs. Flood is a term that can be used to describe any type of water overflow while flash floods are specific to broken dams, overflowing lakes and clogged rivers. The word flood both stands for their meaning.
