Answers
Answer:
75% brown, 25% white
Explanation:
This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).
According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.
Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:
¾ or 75% brown and ¼ or 25% white

Answer:
In many mammals, a developing embryo is nourished through the placenta. ____ is a connection with the mother. Later, a newborn takes in food produced by the blood artilleries of the mother. Unlike a young mammal, an insect or amphibian undergoes metamorphosis which is a series of dramatic changes in body shape and form.
In many mammals, the placenta, which connects the mother and the embryo, provides nutrition to the growing embryo. Oxygen and nutrients can be exchanged between the mother and foetus thanks to the placenta.
What is the mode of nourishment of an infant ?The infant then consumes nourishment made by the mother's milk. This milk, which the mother's mammary glands make, is nutrient- and antibody-rich and aids the infant's growth and development.
An insect or an amphibian goes through metamorphosis, which is a sequence of significant changes in body structure and form, unlike a newborn mammal. The insect or amphibian completely changes during metamorphosis from a larva or tadpole to an adult form the rearrangement of tissues and cells.
The bug or amphibian's adult form can reproduce and is adapted to its environment. Hormones are what cause this metamorphosis, and it requires.

What is Cysteine?Cysteine is a semi essential proteinogenic amino acid encoded by the codons UGU and UGC.
Cysteine is a residue in a high protein foods and classified as non essential amino acids.
Essential for infants, the elderly and individuals with certain metabolic diseases or suffering from Malabsorption Syndrome.
It is also used as in Industrial sources.
Biologically it functions as Nucleophile and easily oxidized and have antioxidant properties due to the ability of thiols to undergo redox reaction.
Cysteine is considered to be hydrophilic amino acid based on the chemical parallel between its sulfhydryl group and the hydroxyl groups in the side chains of other polar amino acids.

anaerobic, heterotrophic bacteria
Answers
Answer:
Early organisms would have to be anaerobic, as air was likely non existent. This rules out the first two options.
Autotrophic can be called producers, and heterotrophic can be called consumers.
The question states that "did not use oxygen for respiration and were unable to make their own food"

What are resources a living thing needs to survive? Are these resources limited or unlimited?
Answers
Answer:
The basic resources a living organism needs to survive are sustinence, shelter, and heat. Sustinence is not an unlimited source and wild animals have to hunt to get their food, and if they hunt too much, the food chain will fall out of balnce to where there is no more of that species.
Shelter or safe homes can also be limited, from animals that find natural spots, or make their own homes out of resources, it can be difficult to not be constantly exposed to the natural environment.
Heat is dependant on climate, and is provided by the sun. Nonetheless, in the winter, it isn't reliable, and in the summer, animals may overheat. In conclusion overall, all of these resources are limited or depending on such circumstances.
How do mammals conserve their heat?
Answers
Answer:
with hair or fur
Explanation:
All mammals are endothermic. They conserve body heat through their hair and fur.
What are endothermic animals?Those animals that can regulate their body temperature are known as endothermic or warm-blooded animals. They can survive even when the temperature fluctuates during seasonal changes. They can live in various climates.
When the body temperature of a mammal increases too high then this condition is called hyperthermia, and body temperature reduces too low, then it is called hypothermia.
Hypothalamus is a part of the brain that maintains the temperature of the body, it is responsible for heat production and heat loss. In mammals, heat generates during cellular metabolism. This process is called thermoregulation.
Hence, this is how mammals conserve their body heat.
