Answer:
All birds start their lives inside an egg. When some birds hatch from the egg they are covered in downy feathers, and they are able to run around and find their own food. Many ground-living birds, such as pheasants and ducks, develop in this way.
Compared with mitosis, the process of meiosis results in daughter cells that are-
A. haploid cells with the same number of chromosomes as the parent cells
B. haploid cells with a smaller number of chromosomes than the parent cells
C. diploid cells with a smaller number of chromosomes than the parent cells
D. diploid cells with the same number of chromosomes as the parent cells
Answer:
Explanation:
eAnswer: Haploid cells with a smaller number of chromosomes than the parent cell

if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expalin with the help of a chart
Answer:
Blue Eyes Are: Recessive
Explanation:
The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. I hope this helps :) Good luck on your assignment!!!
A primary air pollutant is put directly into air by human activity.What is a secondary air pollutant
Answer:
Acid Rain
Explanation:
Acid rain, which is made up of several acidic compounds, forms when sulfur dioxide and nitrogen dioxide react in the air with water, oxygen and other chemicals. On the ground, acid rain damages plants and trees and increases the acidity levels of soils and bodies of water, causing damage to ecosystems. Acid rain also causes decay to buildings and can irritate the eyes and airways.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
Phenotype: 3 black mice: 1 brown mice
Genotype: 1 BB: 2Bb: 1bb
Explanation:
This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.
If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, Bb, Bb, and bb
- The phenotypes of this cross is 3 black mice: 1 brown mice
- The genotypes of the cross is 1 BB: 2Bb: 1bb

Answer:
Eventually, enough CO2 escaped from volcanoes to begin a period of global warming; melting opened a great variety of new niches. When CO2 levels were high, they created a greenhouse effect. More heat was trapped on Earth's surface, and the climate became warmer.

What would "two pairs of chromosomes in the original cell" look like?
Answer:
Two X chromosomes for females and one X and one Y chromosomes for males.
Explanation:
the human body has 23 pairs of chromosomes, or 46 in total. This includes two sex chromosomes : because each chromosome has a pair, these cells are called "diploid" cells .
(d) State the importance of mitosis in the growth of a multicellular organism, such
as a
flowering plant or a mammal.
Explanation:
Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation.

What was the laws of heredity
Answer:
Mendel's Laws of Heredity are usually stated as:
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.
Explanation:The genetic experiments Mendel did with pea plants took him eight years (1856-1863) and he published his results in 1865. During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and type. Mendel's work and his Laws of Inheritance were not appreciated in his time. It wasn't until 1900, after the rediscovery of his Laws, that his experimental results were understood.

Answer:
Producers such as acacia trees and plants!
Answer:

Explanation:
i learned this last year!
autotroph is a organism that can produce its own food using light, water, carbon dioxide, or other chemicals.Why? well because autotrophs produce their own food, they are sometimes called producers.but there are different kinds of autotrophic organisms.

What is fossil fuel?
Fossil fuels has been result of the biological processes as heat and pressure from the Earth's crust that decomposed these organisms into one of the three main kinds of fuel and these are oil which is also called petroleum, natural gas, or coal.
The origin of the fossil fuels has the anaerobic decomposition of the buried lifeless organisms, that containing natural molecules is created through photosynthesis. The conversion from those materials to excessive-carbon fossil fuels commonly require a geological method of millions of years.
Biological methods are defined as the processes that are very crucial for an organism to live, as well as that shape its capacities for interacting with its surroundings. The organic processes has been made of many chemical reactions or the different events that use to concerned within the persistence as well as the transformation of lifestyles forms.
Therefore, Biological approaches either aerobic or the anaerobic which is based upon the environmental necessities of the microbial consortia.

Sexual reproduction in animals depends on the production of gametes.
Which of these processes produces gametes in animals? *
Mitosis
Fertilization
O Meiosis
Binary fission
The process that produces gametes in animals is meiosis.
What is MeiosisMeiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.
During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.
