What can you tell about the sex of this person where the chromosomes came from?
Answer:
Females have two X chromosomes in their cells, while males have both X and a Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome. This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs.

Two atoms have the same number of protons but different numbers of neutrons. These atoms are:
A. electrons
B. isotopes
C. molecules
D. radiation
tysm!
Answer:
isotopes
Explanation:
If two atoms have different numbers of protons, they are different elements. However, if two atoms have the same number of protons, but different numbers of neutrons we refer to them as isotopes. Two terms we use to identify nuclides (isotopes) are atomic number and mass number.

An organism's physical appearance is called?
Answer: phenotype. An organism's physical appearance, or visible traits. genotype. An organism's genetic makeup, or allele combinations.
The physical appearance of an organism is called its phenotype.
What is the term used to describe an organism's physical appearance?An organism's physical appearance also known as its phenotype refers to the observable characteristics that result from the interaction between its genetic makeup (genotype) and environmental influences. These traits can include features such as size, shape, color, and behavior.
The phenotype is the manifestation of an organism's genes and how they are expressed and it vary both within and between species. Studying phenotypes is important for understanding genetic inheritance, evolution and the overall diversity of life on Earth.

If the pig is on its back, the one doing dissection would say the pig is on the
surface.
dosral
ventral
medial
lateral
Answer:
Ventral
Explanation:
This is because when you want to dissect a pig, it's back is place on a dissecting tray and it's belly side is up which is the ventral side. With the ventral side, dissection will be easy and the major organs and systems can be observed easily as they will be rightly viewed because they are obvious and rightly placed at belly side up.

Do the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell?
Answer:
Yes.
Explanation:
Yes, the positive charges on both calcium ions and sodium ions will responsible for the movement of these ions into or out of the cell because the membrane has negative charge which attract these positively charged calcium ions and potassium ions. These difference concentrations of sodium and potassium in the cell are due to the activity of cell membrane active transport system which moves sodium out of the cell and potassium into it.
Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.
What do you mean by Diffusion?Diffusion may be defined as a process resulting from the random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.
The membrane of a cell possesses a negative charge, so it attracts these positive charge ions and makes a concentration difference that leads to the process of active transport through which sodium moves out of the cell and potassium into it.
Therefore, Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.

Answer: Kingdom:Eubacteria
organism name: kelp
Explanation: its kelp in the kingdom classification bacteria
Answer:
Escherichia coli.
Explanation:
Escherichia coli (E. coli) is a gram negative, rod shaped and facultative anaerobic bacterium that lives in large intestines of mammals. It is unicellular or single celled and prokaryotic organism. It reproduces asexually by binary fission.
It does not have nuclues or membrane bound organelbecause it is prokaryotic.
Therefore,
Escherichia coli lives inside large intestines of mammals.

Talonha
Matching: Brain Functions
Answer:
Movement: Parietal
Conscious thought: Cerebral Cortex
Personality: Frontal
Speech/language: Cerebrum
Vision: Occipital
Memory: Temporal
Explanation:
The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision. The temporal lobe processes memories, integrating them with sensations of taste, sound, sight and touch.

Why is flower is reproductive organ
Answer:
The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

Answer:
6. Current = 8.33 Amps
7. Energy = 1200 Joules
Explanation:
Given the following data;
6. Power = 1000 Watts
Voltage = 120 Volts
To find the current flowing through;
Power = current * voltage
1000 = current * 120
Current = 1000/120
Current = 8.33 Amps
7. Power = 900 Watts
Time = 45 minutes to hours = 45/60 = 0.75 hours
To find the energy consumption;
Energy = power/time
Energy = 900/0.75
Energy = 1200 Joules
Is it more likely that the T. Rex would have a 3-chambered heart or a 4-chambered heart and why?
Question 14 options:
A 3-chambered heart because the caiman also has a 3-chambered heart and the T. Rex is most closely related to the caiman.

Period of a wave refers to...
Answer:
The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.

How does flooding affect the soil layer of the
ecosystem?
Answer:
Changes from flooded to drained conditions in soils stimulate changes from aquatic to terrestrial vegetation and decrease the algal contribution to total primary production. Drainage of organic soils then has the effect of removing a source of net primary production (algae) and carbon sequestration
