state three ways in which a sperm cell differs from an egg cell
Answer:
Like a sperm cell, the egg contains a nucleus with half the number of chromosomes as other body cells. Unlike a sperm cell, the egg contains a lot of cytoplasm, the contents of the cell, which is why it is so big. The egg also does not have a tail.

Explanation:
Acid precipitation may change lakes by a. making phosphorus more available to plants, thereby increasing productivity. b. making nitrogen more available to plants, thereby increasing productivity. increasing populations of nitrogen-fixing microorganisms. . accelerating the carbon cycle within lakes. causing the local extinction of species that cannot tolerate
Answer:
causing the local extinction of species that cannot tolerate.
Explanation:
Acid precipitation may change lakes by causing the extinction of local species that cannot tolerate the acidity of the water. The acid precipitation damaged the skin of the aquatic organism as well as internal body structure of various organisms. Acidic nature of water is not good for all organisms except some resistance organisms due to their adaptability so we can conclude that extinction of species occur that has no resistance.

Erythrocytes, leukocytes, and thrombocytes respectively refer to Red blood cells, white blood cells, and platelets.
What is Erythrocytes?Erythrocytes (red blood cells or RBCs) are anucleate, biconcave cells, filled with hemoglobin, that transport oxygen and carbon dioxide between the lungs and tissues.
Leukocytes are part of the body's immune system also known as the white blood cell. They help the body fight infection and other diseases.
Thrombocytes are pieces of very large cells in the bone marrow called megakaryocytes or blood platelets. They help form blood clots to slow or stop bleeding and to help wounds heal.
Thus, Erythrocytes, leukocytes, and thrombocytes respectively refer to Red blood cells, white blood cells, and platelets.

How did the mass extinction that killed the dinosaurs affect the evolution of mammals?
Answer:
With dinosaurs no longer eating them, mammals made quick evolutionary strides, assuming new forms and lifestyles and taking over ecological niches vacated by extinct competitors. ... Sixteen mammal species were discovered, with skulls and other bones fossilized after being buried in rivers and floodplains.
Explanation:
Mass extinctions in across North America and Australia coincide with human migration. With our understanding of populations, which is most likely true about mass extinctions
Answer:
Mass extinction occur when the environment is not favourable.
Explanation:
Mass extinctions occur on the earth when there is sudden change in the environmental conditions for an organisms that is not good for the survival of that particular organisms so they extinct from the earth surface. The example of mass extinctions are dinosaurs. These dinosaurs were extinct due to change in their environment that decreases the availability of food for them so due to no available food, the dinosaur extinct from the earth.
4. Many commercial grow lights deliver light mostly in the yellow/red part of the spectrum, along with smaller portions of all other visible light. Why would a grow light such as this promote plant growth and reproduction (flowering and fruiting) or is this a con job?
Answer and Explanation:
These lights can, in fact, promote the growth and reproduction of plants.
This is because growth, chlorophyll production, flowering and fruiting only occur if the plant is exposed to a band of light with 640-720 nm. Plants receive this band of light naturally through the sun, but when solar energy is not available it is possible to use cultivation lamps that emit this type of light band, which corresponds to the yellow/red spectra.
Hospital patients often receive medications, nutrients, and water intravenously (IV), which means they are injected directly into the patient’s veins through a needle. IV fluid is not pure water, but is instead an isotonic saline solution (water containing NaCl). What do you suppose would happen to the blood if pure water was used as IV fluid instead of saline solution?
Answer:
Explanation:
It would be a terrible idea to give pure water instead of saline solution. Pure water lacks any naturally occuring minerals or solute so when it is injected in your veins, this causes your blood cells to become hypotonic (essentially water enters your RBC via osmosis as your RBC will have higher solute concentration) which usually results in hemolysis (rupture of RBC) and can be fatal.

How many cells are produced at the end of meiosis?
A.1
B.2
C.4
D.6
Answer:
C.4 is the answer
Explanation:
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid because it has half the number of chromosomes as the original parent cell.-

Explanation:
Sickle cell anaemia is an inherited autosomal recessive
condition caused by a mutation in the haemoglobin
subunit beta (HBB) gene. A male and female who are
phenotypically normal, discover through genetic testing
that they are both carriers of a HBB mutant allele. What is
the probability that their first child will be biologically
female and phenotypically normal?
Answer:
1/8 (12.5%)
Explanation:
An autosomal recessive disease is an inherited disease in which an individual need to receive both defective alleles at the same gene locus to be expressed in the phenotype. In this case, both parents are carriers of the recessive mutant allele associated with the sickle cell anaemia trait, thereby both parents are heterozygous, ie., each parent has one copy of the normal allele 'H' and one copy of the defective mutant allele 'h' associated with this condition. In consequence, their first child has a 1/4 (25%) chance of having sickle-cell anaemia. Moreover, the chance of having a girl is 1/2 and the chance of having a boy is 1/2, thereby the final chance of having a girl sickle cell anaemia individual is 1/4 x 1/2 = 1/8 (12.5%).
- Parental cross for sickle cell anaemia trait = Hh x Hh >>
- F1 = 1/4 HH (normal); 1/2 Hh (normal); 1/4 hh (sickle cell anaemia) >>
- Sex proportion of sickle cell anaemia individuals = 1/8 female sickle cell anaemia individuals + 1/8 male sickle cell anaemia individuals (1/8 + 1/8 = 1/4)
According the cell theory, can you create a cell by combining molecules in a laboratory?
Answer:
only if you have the materials

Which of the following would be an accurate food chain that could be found in the
tropical community?
A) cougar --> turtle --> banana
B) insect --> frog --> ocelot --> parrot
C) fruit --> turtle --> cougar
D) vegetable --> insect --> mushroom
Answer: B
Explanation:
The animals that live in tropical areas are in option B. Cougars can not live in the tropics, they live in the cold biomes. In the tropics, there are many insects, and frogs eat them. Ocelots eat the frogs, and the ocelots are eaten by parrots. The rest of the options are valid food chains, but they would not function in the area of tropics. The answer to the question is option B.
