In peas, long stem (A) is dominant over short stem (a). A heterozygous, long stem plant (Aa) is crossed with a homo-zygous, short stemmed plant (aa).
Which of the above squares represent plants that are heterozygous?
Question 9 options:
Box 1
Box 1 and box 2
Box 1 and box 3
Box 2 and box 3
Answers
Answer:
Box 1 and box 3
Explanation:
[tex]\huge\boxed{\textbf{Box 1 and Box 3}}[/tex]
_____________________________________[tex]\Large\textbf{Phenotype:}[/tex]
It is the physical appearance of the trait, whether the plant has Long stem or short stem.
[tex]\Large\textbf{Genotype:}[/tex]
A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or h o m o-zygous, recessive or dominant. This question is basically based on the Genotype, asking for the heterozygous plants which is a genotypic characteristic.
_____________________________________Alleles:Allele Long stem A is dominant over short stem a
Genotype of Parent Pea PlantsPea Plant 1 has genotype Aa
Pea Plant 2 has genotype aa
_____________________________________[tex]\Huge\text{Question:}[/tex]The question asks for how many heterozygous plants are present in the punnet square of pea plant 1 and pea plant 2.
Heterozygous PlantsHeterozygous Plants means those plants which have two different alleles that means One dominant allele (i.e. A here) and One recessive allele (i.e. a here). These Organisms inherit a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.
If we look at the punnet square given in the attachment, the Box 1 and 3 have genotype Aa which is a HETEROZYGOUS DOMINANT PLANT while box 2 and 4 have a genotype aa which is a HOMO-ZYGOUS RECESSIVE PLANT thus the answer is Box 1 and 3

Answers
Answer: You picked the correct answer, "They all inherited their traits from a common ancestor."
Explanation: Well, one I had a test on this question too and I got it right. Second, if all species shown have something in common (structures) than they most likely got it from a common ancestor.
They all inherit their traits from a common ancestor. So, the correct option is C.
What is an Ancestor?An ancestor is a parent or the parent of an antecedent, commonly referred to as a forefather, fore-elder, or forebear. Each individual from whom one is born is an ancestor. The individual who has received an estate, according to law.
Anybody we are descended from is an ancestor. To descend in a family implies to "come from." The parents, who in turn descended through their parents, who in turn descended from the parents, and so forth. The ancestors are the line of parents and kids.
Your ancestors are your mother, father, and grandparents. If matrilineal descent is practiced in the culture or civilization, your mother and grandmother are the ancestors but not your dad or grandfather. They all derive their characteristics from an in this instance.
Therefore, the correct option is C.

Answer: I believe the answer to be a.
Explanation: The symptoms listed are cause of a urinary tract infection, so the most likely answer would have to do with the one having to do with the urinary tract and can often cause a very hideous infection.
Stanimar most likely contract his nosocomial infection through the fact that involves the mechanism of a urinary catheter was not properly sterilized before it was used. Thus, the correct option is A.
What is Nosocomial infection?Nosocomial infection may be defined as a form of healthcare-associated infection that is acquired during the process of receiving health care that was not present during the time of admission.
Some common types of Nosocomial infection include urinary tract infections, respiratory pneumonia, surgical site wound infections, bacteremia, and gastrointestinal and skin infections.
The nosocomial infection generally spread through the pathogens like Staphylococcus aureus, Pseudomonas aeruginosa, and E. coli.

Which of the following is typical of aerobic respiration?
decreases a plant’s weight
contains two stages, glycolysis and fermentation
produces methane as a byproduct
produces little energy
Answers
Answer:
decreases a plant’s weight
Explanation:
Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.
Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.
Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.
Hence, the correct answer is "decreases a plant’s weight".
According to the kinetic theory of matter, how many particles that make up a substance are constantly in motion?
Answers
Answer:
D
Explanation:
According to the kinetic theory of matter, option D. all the particles that make up a substance are constantly in motion.
The Kinetic Theory of Matter states that all matter is made of particles that are atoms and molecules that are constantly in motion in the substance, therefore, particles of all matter have kinetic energy.
Some particles have more kinetic energy than other particles due to fact that all particles of matter do not move at the same speed even though particles of matter are constantly moving.The temperature of matter or object is the average kinetic energy of the particles in an object.Thus, the correct answer is - option D. all the particles.

B.
Laws that improve air quality and restrict pollution.
C.
Increasing the number of factories that burn coal into the air.
D.
A disease that infects the light peppered moths and not the dark.
Answers
Answer:
The correct answer is - option B. laws that improve air quality and restrict pollution.
Explanation:
The dark peppered moths were the adaption of the light peppered moths due to the change in the environmental condition of increased pollution that made tree bark dark in color and allows birds to easily prey on the light peppered moths.
This leads to natural selection and light moths become dark but the after Clean Air Act was that there was less pollution then there is less soot in the air, so trees were less black which result in the Light-colored moths would increase, and dark-colored moths would decrease.

Give two examples of phospholipid soluble molecules? How can these molecules move across the cell membrane? What affects the direction of their movement
Answers
Answer:
1. Only small uncharged molecules can diffuse freely through phospholipid bilayers (Figure 2.49). Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. 2. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). 3. Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.
Explanation:
Hope this helps. ^_^
Answer:
Examples include steroids and Vitamins
Phospholipids ,as the name implies fall under the category of lipids. Phospholipids have a hydrophilic "head" which has a strong attraction to water molecules.The hydrophilic head contains a phosphate group which allows for reactivity with water molecules.
Phospholipids also contains two hydrophobic "tails" which has a strong repulsion to water. The tails are derived from fatty acids and are joined by a glycerol molecule. These compounds are less reactive to water molecules .
These properties make phospholipids to be soluble in both water and oil which favors the movement of molecules such as Steroids and Vitamins in and out of the cells through the process called Diffusion.
The direction of movement depends on the concentration of molecules as they usually move from a region of high concentration to a region of lower concentration to ensure there is equilibrium and proper functioning of cells.
