In codominance, two alleles can be simultaneously expressed. The correct option is D. 1/2 homozygous brown (BB), 1/2 heterozygous agouti (BW).
What is codominance?Codominance is an inheritable pattern in which two alleles can be simultaneously expressed.
In these situations, heterozygous individuals can express two phenotypes, each of them coded by one allele.
Heterozygous individuals' phenotype is an additive expression of their parents' genes.

Ram gives his dog a piece of bread to eat. The dog picks it up and starts eating. Which of the following organ systems of the dog is active when it eats the bread?
1. digestive system
2.nervous system
3.skeletal system
A. only 1
B. only 1 and 2
C. only 1 and 3
D. all -1, 2 and 3
Answer:
D, all 3.
Explanation:
The nervous system sends a message to the nerves in the dog's bones (which are a part of the skeletal system) to pick up the food. The digestive system breaks down the food.
The organ systems of the dog that is activated when it eats the bread are the digestive, nervous, and skeletal system. Thus, the correct option is D, i.e. all of the above.
What is an Organ System?An organ system may be defined as a cluster of organs that work together to perform specific bodily functions significantly.
When a dog eats bread, the digestive system converts this piece of bread into simpler substances that are absorbed by the small intestine. This is the direct function of the organ system.
Apart from the digestive system, the nervous system sends the message through the impulse to the bones which are part of the skeletal system to grab the nutrients as well as energy for them.
Therefore, the correct for this question is D.

We get chemical energy from foods, which we use to run about, and move and talk (kinetic and sound energy). Chemical energies are stored in fuels which we burn to release thermal energy - this is one way of making electricity, see Electricity for more information.
his nutrient is cycled between living things and the soil. Plants absorb this nutrient from the soil and turn it into organic compounds through assimilation. Animals eats the plants and pass the nutrient through the food chain from one organism to another. When the animal dies, it decomposes and returns the nutrient back to the soil. The nutrient can also enter the soil through weathering and erosion.
The nutrient is phosphorus
The phosphorus cyclePhosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).
The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.
Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.
When plants and animal die, their body decomposes and the phosphorus in them enters the soil.

While the adult carp prefer slow moving water, they look for high, fast moving water when laying eggs (spawning). They lay hundreds of thousands of eggs at a time, which means populations grow and spread quickly. Because of this, they can quickly out-compete native species, and put ecosystems in danger.Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.Asian carp cause serious damage to the native fish populations in the lakes and rivers that they infest because they out-compete other fish (video, 1 min) for food and space.

During germination, starch stored in the cotyledons is broken down .
describe how the breaking down of starch occurs.
Answer:
During germination, starch is degraded by the combined actions of several hydrolytic enzymes such as α-amylase, β-amylase, and α-glucosidase to provide energy for the embryo.
Enzymes hydrolyze starch into simpler sugars during germination, providing a source of energy for seedling growth.
Plant seeds convert their cotyledons' starch into sugars during germination. The seedling needs energy until it can photosynthesise and manufacture its own nutrition. Amylases digest starch. Amylases hydrolyze starch into glucose and maltose. Starch hydrolysis disrupts glycosidic connections between glucose molecules by adding water molecules.
The seedling can easily transfer and convert glucose and maltose into energy through cellular respiration. This energy powers metabolic processes and development when the seedling emerges from the seed coat and grows roots and branches. The plant converts stored starch into sugars to give energy during early development before photosynthesis takes over.

If you were given a cube of modeling clay, how would you shape it to have the greatest surface area-to- volume ratio?
To have the greatest surface area to volume ratio, it would be best to flatten the clay and create numerous projections.
The quantity of surface area per unit volume of an object or collection of objects is known as the surface-area-to-volume ratio (also known as the surface-to-volume ratio or abbreviated as SA:V). A cell's volume increases proportionately more than its surface area as its size decreases. As a result, the surface area to volume ratio is higher for smaller objects. For cells, a high surface area to volume ratio is crucial. There is more plasma membrane compared to the interior of the cell when surface area exceeds volume. This makes it feasible for materials to be moved into, out of, and around the cell as effectively as possible.The fact that a surface area must be sufficient to hold the volume helps to explain why most cells are tiny in size.
