Is it the paternal or maternal gamete that determines sex? Explain
Answer:
Sex of the baby is determined by the paternal gamete
Explanation:
Sex of the baby is determined at the time of fertilization as during this time the sperm from the male and the ovum from the female fuse with each other.
Women are homogametic and produce one type of ovum (maternal gamete) (22+X).
However the male companion is heterogametic and produces two types of sperm (paternal gamete) i.e. one 22+X and the other 22+Y in identical amounts.
Therefore the zygote would be off (44+XX or 44+XY) chromosomes depending on which kind of sperm fertilizes the ovum.
The zygote carrying 44+XX chromosomes would be a male baby whereas the other carrying 44+XY would be a female baby.
Therefore the sex of the baby is determined by the paternal gamete and not by the maternal gamete at the time of fertilization.
The mother gives an X chromosome to the child. The father may contribute an X or a Y. The chromosome from the father determines if the baby is born as male or female.
6. Detail: If resources need to make a product are very
generally
generally
then the supply is
likely to be more plentiful and easily accessible, which can result in a decrease in the product's price.
This is due to the fact that it is simpler for producers to access the materials they need to manufacture the product due to the widespread availability of resources, and price reductions due to competition among suppliers.
However, additional elements like demand, the state of the market, and governmental laws will also have an impact on the actual supply and price of a product.
A product's supply is often poor if the raw materials required to create it are extremely limited or uncommon. When resources are few, there is a low supply since production capacity is constrained.
Due to the product's scarcity, this frequently results in an increase in price, which can present problems for both producers and customers.
On the other side, if resources are plentiful, there may be a huge supply of the product, which could lead to reduced pricing because it is easier to produce. In the end, the supply of a product on the market can be significantly impacted by the cost and availability of resources.

What ratio of guinea pigs in the offspring would you predict from a Ss x ss cross?
All the offspring will have a recessive allele, but only half of them will have a dominant allele. Therefore, the predicted ratio of genotypes in the offspring is 1:1 for Ss:ss or 50%:50%.
What is Offspring?
Offspring refers to the biological or genetic descendants of an organism, usually produced through sexual or asexual reproduction. In the context of sexual reproduction, offspring are the result of the fusion of genetic material from two parents, each contributing half of the offspring's genetic makeup. The offspring inherit a unique combination of genetic traits from their parents, which determine their physical and behavioral characteristics.
Assuming "S" is dominant and "s" is recessive, the genotype of the parent Ss can produce two types of gametes, S or s. On the other hand, the genotype of the parent ss can only produce one type of gamete, s. Therefore, the possible genotypes of the offspring from this cross are:
Ss (offspring with one dominant and one recessive allele)
ss (offspring with two recessive alleles)
To determine the ratio of genotypes in the offspring, we can use a Punnett square:
| S | s
--|---|--
s | Ss| ss
s | Ss| ss

Amoeba are freshwater protists. What would happen to the amoeba if it was removed from the freshwater and placed into a saltwater pool? EXPLAIN. (Hint: think about osmosis)
Answer:
Amoeba are single-celled organisms that live in freshwater environments. To regulate osmotic pressure, most freshwater amoebae have a contractile vacuole (CV) that expels excess water from the cell. Water is transferred across the amoeba’s cell membrane by osmosis. Without a CV, the cell would fill with excess water and eventually burst.
If an amoeba was removed from freshwater and placed into salt water, it would be exposed to a hypertonic environment. This means there would be a higher concentration of solutes outside the cell than inside. In this case, water would move out of the cell by osmosis to try to balance out the concentration of solutes on either side of the membrane.
Explanation:
When an amoeba is placed into a hypertonic environment, such as salt water, the concentration of solutes outside the cell is higher than inside. This causes water to move out of the cell through the process of osmosis, which leads to the cell shrinking and becoming dehydrated. Without a contractile vacuole to expel excess water, the amoeba would eventually die due to dehydration.
Which statement about radiation is FALSE? The polar regions do not receive as much solar radiation as the equator. Radiation can travel through the vacuum of space.

With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke and began the scientific study of cells. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration and the idea of cells as a fundamental unit of life. The cell theory was eventually formulated in 1839.
The three tenets to the cell theory are:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.
Which TWO of these contributed to formation of the cell theory?

- extracellular pathogens
- intracellular pathogens.
-parasitic worms
- allergens
The immune response mediated by cells is mostly used by the body against intracellular pathogens.
What defenses does the body have against extracellular pathogens?Infection is prevented or delayed by innate immunity, which is mediated by neutrophils, NK cells, NKT cells, T cells, complement, and microbicidal chemicals, until adaptive immunity may also react to the pathogen. Antibody-coated extracellular substances are eliminated by complement- and antibody-mediated processes.
Is intracellular pathogen immunity possible with cells?According to the accepted wisdom in the area, humoral immunity is crucial for defense against extracellular infections whereas cell-mediated immunity (CMI) is more significant for defense against intracellular pathogens.
