Explanation:
Myrmecia pilosula was originally described as a single species, however, after closer examination, it was determined to consists of several distinct, closely related, physically similar species. Females have chromosome numbers of 2, 18, 20, 32, 48, 60, 62, and 64. Assume that a cross is made between a female of species (A) with 48 chromosomes and a male species (B) with 10 chromosomes (males are haploid and transmit all their chromosomes to each sperm cell). How many chromosomes would be expected in the somatic cells of the hybrid female offspring?
Answer:
The correct answer is "34".
Explanation:
The ant Myrmecia pilosula is a special case of sexual reproduction, where the females produce gamete cells with half the chromosomes of the somatic cells and the males are haploids that transmit the whole number of chromosomes in their gametes. Therefore, the somatic cells of the hybrid female offspring that results from the cross of a female ant with 48 chromosomes and a male with 10 chromosomes would have 34 chromosomes. This result from half the number of chromosomes of the female (24) plus the total number of chromosomes of the male (10).

Explanation:
Glucose is present in blood plasma at a concentration of approximately 80 mg/dL. A typical 70 kg human has approximately 5 L blood, which is 55% plasma. Using the glucose concentration of Sprite that you calculated in the previous question, how many mL of Sprite does a human need to drink to reach a plasma glucose concentration of 80 mg/dL, assuming none is mobilized?
Answer: 48.93 mL of sprite
Volume of blood in 7 Kg human = 5 L
Percentage of plasma in blood = 55%
Volume of plasma in 5 L blood = (1 L = 10 dL)
Concentration of glucose in plasma = 80 mg/dL
Amount of glucose present in 27.5 dL : 80 mg /dL × 27.5 dL= 2200 mg
Let the volume of sprite with 2200 mg glucose be x
Concentration of glucose in sprite = 44.96 mg/mL
Explanation:
Phenotype determines genotype. If false, make it a correct statement.
A. True
B. False
Answer:
The correct answer is B. False
Explanation:
The genotype of an organism determines its phenotype. Phenotype is constituted by observable characteristics of an organism. These characteristics are codified by genes, and the combination of the differents variants of a gene which codify a phenotipic characteristic constitutes the genotype. For example: eyes color is a characteristic. Its is codified by variants of a gene. The combination of two variants of a gene gives a genotype, which codifies for the phenotype 'blue eyes'.

What is the structure of a water molecule ?
Water occupy around 70% of the earth’s surface, it make up about 95% of the living organisms.
Each water molecule is composed up of one molecule of oxygen and two molecules of hydrogen by forming a covalent bond .
A strong bond of attraction between nucleus of the oxygen nucleus and electrons of hydrogen has been seen which form an angle 105° between hydrogen atoms
Due to this asymmetry in shape water has a strong property of strong dipole movement that is highly polarized molecule with both positive and negative charges.
It is very cohesive in nature by developing a strong bonding with itself, and also adhesive in nature.
It shows high boiling point as hydrogen- oxygen bond highly polar and
Hydrogen atoms are present at two corners with a tetrahedron shaped which gives water a high polarity.

Because the cell membrane is made of two layers of lipids it is called a..?
Answer:
The lipid bilayer.
Explanation:
It is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.
Cell membrane is made of two layers of lipids it is called lipid bilayer.
What is lipid bilayer?The lipid bilayer is a fundamental component of all cell membranes. It is vital for identifying cell boundaries because of the barrier that its structural components offer.
The structure is called a "lipid bilayer" because there are two layers of fat cells arranged in two sheets, and the lipid bilayer, which surrounds all cells and provides the structure of the cell membrane, is usually about five nanometers thick.
The lipid bilayer's structural makeup explains how it acts as a barrier. Lipids are fats that are soluble in oil but not in water. The lipid bilayer's structure is provided by two crucial areas of a lipid.

What might happen to biodiversity in area 1 if the new bird species moved into the area
Answer:
New bird species may alter the ecosystem and modify the trophic chain when they become invasive, leading consequently to the loss of biodiversity
Explanation:
Invasive (also known as alien) species are non-native species capable of spreading into a new area where they have a drastic impact on the ecosystem. An invasive species may cause an important loss of biodiversity and modify the food web in an ecosystem by replacing native species. Examples of invasive bird species include the house sparrow, European starling, cattle egret, rock pigeon, etc. Nonetheless, it is important to highlight that not necessarily new bird species will become invasive (it will depend on their effects on the ecosystem).

1. The type of organism that possess cell exposed to the environment from all sides is.
O unicellular organism
O multicellular organism
O plants
O animals
Answer:
unicellular organism
Explanation:
The type of organism that possesses a cell exposed to the environment from all sides is unicellular organism, option A is correct.
Unicellular organisms, as the name suggests, are composed of a single cell that functions as both the basic unit of life and the interface with the environment. These organisms, including bacteria, protozoa, and some algae, carry out essential processes such as respiration, nutrition, and reproduction within this singular cell.
Due to their simplicity and direct exposure, they can efficiently exchange substances with the surrounding environment from all sides. In contrast, multicellular organism, like plants and animals, possess specialized cell types organized into tissues and organs, limiting direct environmental contact to specific cell surfaces. This fundamental difference in cellular organization is a key characteristic that distinguishes unicellular organisms from their multicellular counterparts, option A is correct.

Organisms with a narrow range of temperature tolerance would most likely be found where ?
Answer:
there is less fluctuation in abiotic factor such as temperature.
Explanation:
Organisms with a narrow range of temperature tolerance would most likely be found where there is less fluctuation of temperature or variation in temperature because the organisms are tolerant to less variation in abiotic factor such as temperature so if the temperature goes very high or low, then the organism is not able to tolerate and die. So we can say that less variation in temperature are the regions where organisms with a narrow range of temperature tolerance can be found.

What is the role of the gametophyte in fernsg?
Answer:
The gametophyte produces the haploid gametes
Explanation:
Ferns are a group of lower plants that also undergo the ALTERNATION OF GENERATIONS in their reproductive life cycle. The plant consists of the SPOROPHYTE and GAMETOPHYTE. The sporophyte is a diploid plant body that produces the haploid spores via meiosis. These spores are released on the sporangium and grow into a haploid GAMETOPHYTE.
The gametophyte produces the haploid GAMETES i.e. male gametophyte (antheridium) produces sperm while female gametophyte (archegonium) produces eggs, which undergo fertilization to produce a diploid zygote that develops into the sporophyte. The cycle begins again.
