Explanation:
How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating season than than their diploid parents, causing reproductive isolation between the two generations. Polyploid offspring produce smaller gametes that disperse farther than the gametes of diploid parents, causing geographic isolation between the two generations. Physiological differences between polyploid offspring and their diploid parents allow them to thrive in different environments, causing geographic isolation between the two generations. Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.

Answer:
Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Explanation:
Speciation is an ecological and biological process through which new species are formed due to isolation.
In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.

Genetically modified organisms include microbes used in biotechnology that possess enzymes promoting antibiotic resistance. This could be a problem given the rise of antibiotic-resistant organisms. However, these engineered microorganisms do not pose a risk to public health. What do you think prevents them from spreading antibiotic resistance to pathogens outside the laboratory
Answers
Answer:
What prevents these microorganisms from spreading resistance outside the laboratory is that they are modified to not survive outside the laboratory environment.
Explanation:
Antibiotic resistant microorganisms are very dangerous and unfavorable, as they leave living beings completely completely defenseless to their attacks. However, there are microorganisms that have been modified in the laboratory, as shown in the question above, and do not present any risk to living beings, even if they develop resistance. This is because the modification that these microorganisms received makes them not survive the environmental conditions outside the laboratory, which causes them to die if they leave the laboratory.

What causes the formation of a cervical plug a testorone b progesterone c luteal d estroge e follicle
Answers
Answer:
b progesterone
Explanation:
The plug is formed as soon as there is implantation of fertilized eggs. The thickness of the cervical mucus becomes different as hormone levels changes in pregnancy.
The progesterone, encourages the production of thick fluid/ mucus which brings about the formation of a plug. This prevents bacteria from getting into the uterine cavity.
Answer: The correct option is B (progesterone).
Explanation:
The cervix is the ring of muscles also called the neck of the uterus in female reproductive system. This protrudes through the anterior wall of the vagina, opening into it at the external os.
After the fertilization of the ovum by the spermatozoa, the uterus prepares for the implantation which results from the secretion of hormones. Under the influence of oetrogen, secreted by the developing follicle, the cells of the endometrium divide rapidly causing the endometrium to build up and thicken.
While the viscosity of cervical mucus changes in response to hormone levels and during pregnancy, progesterone fosters the production of highly viscous mucus resulting in the formation of a plug that forms a physical barrier to bacteria and prevents their ascension into the uterine cavity. This plug is called CERVICAL PLUG.

Luisa went into the bathroom after her sister had a bath. It was full of mist and the mirror was covered with the a lot of liquid drops. What was the mist made of?
Answers
Answer:
Mist is made of water vapor.
Explanation:
The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.

5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.
Answers
Answer
The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.
Explanation:
The brain stem, consisting of the pons and medulla, represent the main respiratory center. According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."
This is an example of a homostastic response controlled by both of the organ systems referenced above.

As native mason bees visit flowers, they spread pollen while also consuming nectar from the plant. This is an example of symbiosis.
true or fasle
Answers
Answer:
True
Explanation:
Symbiosis is a type of relationship or interaction between two different biological organisms/species by which both are benefited. The bees such as mason bees are pollinators. Pollinators are animals (especially insects) that help the development of seeds and the fruit surrounding seeds by the pollination of flowers, i.e., by the transference of pollen from male anthers of a flower to the female stigma. During this process, pollinators eat nectar, which is a sweet energy-rich liquid secreted by flowers. In consequence, both species (i.e., plants and mason bees) are benefited from this interaction.

Entre una planta alta de color purpura (AABB) con otras planta enana de color blanco (aabb), ¿cómo será el genotipo y el fenotipo de la F1 Y F2?
Answers
Answer:
- Alelos:
Locus 1: A (alto); a (enano)
Locus 2: B (púrpura); b (blanco)
- Cruzamiento parental: AABB x aabb
Genotipos F1: AaBb
- Cruzamiento F1: AaBb x AaBb
Fenotipo: 100% plantas altas púrpuras
- Genotipos F2: AABB (1/16); Aabb (1/16); aaBB (1/16); aabb (1/16); AaBb (4/16); AABb (2/16); aaBb (2/16); AaBB (2/16); Aabb (2/16)
- Fenotipos F2: 9/16 A-B- (altas púrpuras); 3/16 A-bb (altas blancas); 3/16 aaB- (enanas púrpuras); 1/16 aabb (enanas blancas)
Explanation:
Un cruzamiento dihíbrido refiere a un tipo de cruzamiento entre dos parentales que difieren para dos pares de alelos (AABB x aabb). Si consideramos dos loci de dominancia completa, un cruzamiento dihíbrido producirá una F1 heterocigota para ambos genes donde la progenie expresará ambos rasgos dominantes. Como resultado de la distribución independiente expresada en la segunda ley de Mendel, La F2 de este tipo de cruzamiento producirá un proporción fenotípica 9:3:3:1; es decir 9 individuos con ambos rasgos dominantes (A-B-), 3 con el rasgo uno dominante (A-bb), 3 con el rasgo dos dominante (aaB-) y 1 con ambos rasgos recesivos (aabb).
Because the imaginary axis of the earth is inclined to the sun at the equator, the northern and southern hemispheres shine in different ways. When it is summer in the northern hemisphere of our planet, then it is winter in the southern hemisphere
Answers
Answer:
Yes.
Explanation:
Yes, when it is summer in the northern hemisphere of earth, then it is winter in the southern hemisphere. This change of season occur due to tilting of earth. The season of northern hemisphere and southern hemisphere are different and opposite to each other because both are present at opposite location on the earth surface. The tilting region experience winter season whereas the other regions experience summer due to direct sunlight.
