In poultry, rose comb is a dominant trait, single comb is recessive. A rose-combed male is mated with two rose-combed females. Female A produces '14 chicks, all rose-combed. Female B produces 9 chicks, 7 rose-combed and 2 single-combed. What are the genotypes of the three parent birds? (There needs to be two Punnet Squares btw)
help pls 3
Answer: The male is Rr. Female A is RR. Female B is Rr.
Explanation: Since single comb is recessive, both parents would have to have the gene. Good luck! :D (I only had markers near me, sorry it doesn't look that good :(
7. What is meant by the saying everything that is psychological is also biological
Answer:
People who work in psychology want to understand human behavior and where it comes from. The mind-body dualism debate is an ongoing discussion on whether or not the psychological activity of an individual is based entirely in their body, or if there is a higher consciousness separate from the body. The debate stretches back hundreds of years in the field of philosophy, where philosophers have argued whether everything is material, or if there is a separate, immaterial part to being human.

What is the difference between natural selection and artificial selection? Explain why?
Answer:
Natural selection is not decided by humans, but aritifical is. In natural selection, the organism that naturally survives will have their selection of characteristics carried onto the offspring. But in artifical, humans decide which characteristics they want from an offsrping for their sepcific need, e.g largest or colour and breed organisms for that characteristic- not to make them survive better.

16. Living things can be classified based on which of these criteria? (Select all that apply.)
oxygen breather
number of legs
reproduces asexually
aquatic
I’ll give brainliest .
Answer:
1)oxygen breather
2)number of legs
3)Asexual reproduction
(i think these are answers )
Explanation:
3)Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually.
2)Living organisms are classified into groups depending on their structure and ... Phylum follows Kingdoms and has many different organisms, including three ... Chordata, which have backbones; Arthropod, which have jointed legs
1) Based on oxygen requirement, organisms are classified into four types: 1. Aerobes are capable of growing at full oxygen tension and many can tolerate elevated levels of oxygen (greater than 21%). Microaerophiles are aerobes that can use oxygen if only it is present at reduced levels in air.

The number of sister chromatids in a human body cell that is entering cell division is ?
Answer:
Since there are 23 chromosomes and each chromosome has 2 sister chromatids, the answer should be 46 in my opinion
The number of sister chromatids in a human body cell that is entering cell division is two.
What are chromatids?Chromatids are identical copies of a chromosome that are formed during DNA replication. Each chromosome consists of a single DNA molecule and during replication the DNA molecule is unwound and each strand serves as a template for the synthesis of a new strand of DNA.
After replication, each chromosome consists of two identical chromatids that are held together by a centromere.
As the cell enters cell division, the chromatids are separated and each is distributed to a separate daughter cell. This process is known as mitosis, and it ensures that each daughter cell receives a complete and identical set of chromosome.

how do greenhouse effect allow for there to be life on earth? Explain
Answer:
A greenhouse effect is when a planets atmosphere gets thicker and warms
Explanation:
As a planet with water's parent star gets brighter every million years, The amount of evaporation increases. these are called greenhouse gasses. greenhouse gasses include water vapor and Carbon. This is why Venus is a burning hell. it was once like earth, but the sun kept getting brighter and brighter, causing clouds to form all over the rock, trapping in more heat, and making it far to hot for even metal. One day this will happen to earth, as well. this is why we have global warming. It can be caused by Co2 from earth's inhabitants and water vapor from it's vast oceans.

If the sperm cell of a fruit fly has 4 chromosomes, then the number of chromosomes in each body cell is:
Answer:8
Explanation:
Number of chromosomes in each body cell is 8.
What do you mean by chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Moreover, chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
Therefore, passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Describe some changes that occurred during the process of human evolution by comparing the first primates to the first hominids?
Answer:Rather, it could look more like one branch or the other branch, or something else entirely. Did the common ancestor of humans and chimps conform to the ape-man myth and live in the trees, swinging from vines? To answer this, we have to focus not only on anatomy but on behavior, and we have to do it in a phylogenetic context.
Which of the following does not represent a condition required for natural
selection to occur?
A)People breeding cows to be larger and have specific coloration.
B)An insect has genetic mutations which allow it to survive being sprayed
with a certain chemical.
C)The carnivorous venus fly trap has adaptations that allow it to live
in areas lacking nutrients in the soil.
D)Bacteria reproduce by binary fissions so fast that populations can
double in every 4 - 20 minutes.
Answer:
A)
Explanation:
Because people breeding cows is not natural
A step that is not part of natural selection is people select which individuals breed and which ones do not.
What is Natural selection?Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.
As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that people cannot determine which individuals breed.
Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.
The other options do form part of natural selection, since they are based on the three premises of this process are the Inheritable characteristics., Genetic variability. The variability of characteristics influences reproduction and survival.
Therefore, A step that is not part of natural selection is people select which individuals breed and which ones do not.

Conduction is the transfer of heat between substances with different temperatures. Heat moves from the warmer to the cooler substance through direct contact.
Answer:
True.
Explanation:
Conduction is a heat transfer method. The heat passes by direct contact between two objects. The heat will go from the object with the higher temperature to the one with the lowest one. We call this temperature gradient. If we analyze the molecular aspect of conduction, we can see that the molecules with higher temperatures have more energy so, they move more. These molecules will collide with the molecules of the other object transferring their energy. As a result, heat passes from the hottest object to the cooler one till the two substances are at the same temperature, there is thermal equilibrium.

gene activity.
cell division.

Answer:
Explanation:
Genes contain specific instructions for how to make proteins within the body.
Epigenetic changes are generally heritable genetic changes that are due to environmental factors, which work by turning genes that already exist in the body 'on' or 'off' depending on these factors.
Meiosis produces gamete cells. This is usually a total of 4 gamete cells which are all part of producing everything required in the reproductive process.
exposure to extreme heat is probably the most likely cause of mutation for E. Coli as it needs a steady 36–40°C for survival.
Changes to body cells affect cell division. This is because genetic mutations cause cells that are designed for normal cell growth to greatly increase which can throw the system off and cause many problems.
