R RR RR
W RW RW
From this cross, there are two possible genotypes: RR and RW. The genotype RR results in a red flower, and the genotype RW results in a pink flower. Since the genotype WW is not possible with this cross, none of the offspring are expected to have white flowers.

All of the following can take material into cells except
O active transport
O exocytosis
O endocytosis
O passive transport
Answer:
The correct answer is - exocytosis.
Explanation:
All of the given options of the transport mechanism are the transport of the substances either into the cell or out of the cell or both. Active transport is the transport mechanism that involves the transports of substances from the lower concentration region to the higher concentration region and utilize energy.
Endocytosis and exocytosis are the forms of active transport, however, endocytosis involves taking material into the cell and exocytosis out of the cell. Exocytosis is the form of active transport as it requires energy to moving materials from within a cell to the exterior of the cell.
Which change is an example of a response to a stimulus?
1.
The pupil of an eye decreases in size in bright light.
2.
A leaf absorbs sunlight in the morning.
3.
The water level of a pond rises on a rainy day.
4.
A dead tree decays after many years.
S
Answer:
1
Explanation:
The example of the response to stimulus is the contraction of the pupil of eye in response to the bright light. Thus, option A is correct.
The stimuli are the things or events that causes the detectable change in the organism. The reaction of the organism with response to the stimuli is measured in terms of sensitivity.
What is a stimulus response?The stimulus response is created when the external event or the thing brings changes in the chemical or physical nature. The response to stimuli are instant reactions.
The decrease in the pupil size with the light as the stimulus is the response of eyes.
Thus, the example of the response to stimulus is the contraction of the pupil of eye in response to the bright light. Thus, option A is correct.

Explanation:
Imagine that you find a layer of rock containing many fossil clams. The layer of rock is 50 km from the ocean. The fossils are about 5 million years old. Clams usually live in shallow ocean water. Based on the fossils, what can you guess about the environment in this area 5 million years ago?
Answer:
No ocean is present 5 million years ago.
Explanation:
There is no ocean or sea in this area 5 million years ago because the land is present where these fossils live but with the passage of time the geography of that place changes and the ocean covered the area and these fossils remain below the ocean inside the layer of land. So we can conclude from the presence of these fossils that there is no ocean present in these regions 5 million years ago .
The area that contains many fossil clams used to covered with ocean water 5 million year ago
Clams are the the variety of shel-fish that are usually found in shallow water and are important to maintain the web of the ecosystem
5 million years ago the area of 50 km was covered with shallow water range but with the time and environmental change area with clams got vanished and with time changed into fossil.
Therefore, the area of 50 km used to covered with ocean water 5 million year ago.

How many anatomical characteristics do Cetaceans share with Mammals?
Answer:
Anatomy suggests that Cetaceans are more closely related to mammals than fish since they share more similarities with the mammals, such as a 4-chambered heart and lungs. What does anatomy say about the ancestry of Cetaceans?
Explanation:
Hope it helps! Correct me if I am wrong :>
Anatomy suggests that Cetaceans more closely resemble mammals. Cetaceans have a 4-chambered heart, lungs to breathe, giving birth to young ones, mammary glands, endothermic, etc.
What are Cetaceans?Cetaceans can be called aquatic mammals and it includes whales, dolphins, etc.
These are one of the most distinctive and highly specialized orders of mammals.
They are more likely to have anatomical characteristics of mammals than fish. As they have a 4-chambered heart, are endothermic, give birth to young ones, and have mammary glands, these are considered under mammals.
Thus, these are the characteristics that Cetaceans share with mammals.

Where I have used the term "chromosome complement," I am simply referring to the "complete" chromosome makeup of the nucleus of a cell in the flowering plant life cycle. The Merriam Webster Third New International Dictionary has many definitions for complement, but the one I am using is "the quantity or number required to fill a thing or make it complete." On the chromosome questions I want the "complete" chromosomes (represented by letters) for various cells and nuclei in the plant life cycle. For example, if ABCD refers to the chromosomes of an egg and abcd refers to the chromosomes of a sperm; then AaBbCcDd refers to the complete chromosomes of a fertilized egg or zygote (ABCD + abcd = AaBbCcDd). In a number of questions I have referred to the chromosome complement of a specific cell or nucleus, such as the zygote. In this case the chromosome complement of the zygote would be AaBbCcDd. The chromosome complement of the embryo would also be AaBbCcDd. Just think of the chromosome complement as the complete chromosome makeup of a cell where large and small case letters stand for the actual chromosomes. If there is one of each letter, then the cell is haploid (e.g. ABCD or abcd). If there are two of each letter, then the cell is diploid (e.g. AaBbCcDd). If there are three of each letter, then the cell is triploid (e.g. AAaBBbCCcDDd). If there are four of each letter, then the cell is tetraploid (e.g. AAaaBBbbCCccDDdd).
In the following questions, the term haploid (1n) refers to one set of chromosomes. This is typically the number of chromosomes found in the single nuclei of sex cells (gametes). In the flowering plant life cycle, this is also the chromosome number of the three nuclei within a germinated pollen grain (pollen tube) and the eight nuclei within an embryo sac. In plants, the haploid part of the life cycle is called the gametophyte. The normal haploid number for a human egg or sperm is 23 chromosomes (n = 23). The term diploid refers to two sets of chromosomes resulting from the union of the sperm and the egg. This is typically the number of chromosomes found in the nuclei of body cells (somatic cells) of a plant or animal. In plants, the diploid part of the life cycle is called the sporophyte. In a normal human, the diploid number is 46 chromosomes (2n = 46). The following link to life cycle patterns may be helpful in understanding the gametophyte and sporophyte parts of a life cycle. In the diagrams, everything above the red horizontal line is diploid (sporophyte) and everything below the red line is haploid (gametophyte). The terms sporophyte and gametophyte are used in the life cycles of plants, fungi and algae, but not animals.
