describe eggs and egg laying in monotremes

Answers

Answer 1
Female monotremes lack a uterus and vagina. Instead, they have a cloaca with one opening, like the cloaca's of reptiles and birds. The opening is used to excrete wastes as well as lay eggs. Monotreme eggs have a leathery shell, like the eggs of reptiles. The eggs are retained inside the mother’s body for at least a couple of weeks. During that time, the mother provides the eggs with nutrients. Platypus females lay their eggs in a burrow. Echidna females have a pouch in which they store their eggs. Female monotremes have mammary glands but lack nipples. Instead, they “sweat” milk from a patch on their belly.

What are three key factors that contribute to a female primate's success at feeding?

Answers

The key factors that contribute to a female primate's success at feeding includes; a) Distribution or location of food; the location of food across the landscape and the amount of energy the the female has to expend to collect food; such that if the food is abundant throughout the forest she will use very little energy in gathering food. b) Quality of food- this reflects the amount of energy provided and the ease with ease with which food can be digested.
c) Availability of food; this explains the reason why many primates are restricted to equatorial regions.

What is the function(s) of atp? provides the energy for respiration provides the energy for photosynthesis stores the initial energy released by respiration provides the energy for all cytoplasmic chemical synthesis a complex molecule from which all other organic compounds are made?

Answers

provides the energy for respiration  and stores the initial energy released by respiration

ATP, the energy currency of the cell, is pivotal for storing and transferring energy to support cellular processes. It is involved in both respiration and photosynthesis, and enables endergonic chemical reactions by providing necessary energy. The regeneration of ATP from ADP or AMP is a critical aspect of cellular metabolism.

Functions of ATP

Adenosine triphosphate (ATP) is often referred to as the energy currency of the cell, playing a crucial role in the storage and transfer of energy. ATP's main function is to provide the energy needed for various cellular processes. It is involved in respiration, where it stores the initial energy released and photosynthesis, where it is one of the end products.

One molecule of ATP contains three phosphate groups, and it becomes adenosine diphosphate (ADP) or adenosine monophosphate (AMP) when these phosphates are detached during energy transfer. This energy is then used to drive endergonic chemical reactions within the cell, which are reactions that require an input of energy. These processes include biosynthetic reactions, motility, and cell division.

ATP is produced by a wide array of enzymes, including ATP synthase, through mechanisms such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation. Regenerating ATP from ADP or AMP is essential, with the energy to do so primarily derived from the catabolism of glucose.

Which forearm bone(s) contribute(s) most heavily to the elbow joint? the humerus the carpal bones the ulna the radius?

Answers

The bone is ulna. The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It runs parallel to the radius, the other long bone in the forearm, and is the larger and longer of the two. The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The radius is shorter and smaller than the ulna.
Final answer:

The ulna and the radius bones contribute most heavily to the elbow joint.

Explanation:

The ulna and the radius bones contribute most heavily to the elbow joint.

The ulna is located on the medial aspect (pinky-finger side) of the forearm, and it is longer than the radius. It articulates with the humerus at the elbow. The radius is located along the lateral (thumb) side of the forearm and also articulates with the humerus at the elbow.

Which organisms is a secondary consumer in this food web?

Answers

In any food chain autotrophs are the producers which synthesizes food using solar energy. Autotrophs are green plants in terrestrial ecosystem. The herbivores which feed on plants are primary consumers and animals which feeds on herbivores are secondary consumer. These are carnivores or omnivores. For example, in forest ecosystem, trees are producers, deer is an primary consumer and lion is secondary or top consumer.    

Final answer:

In the Lake Ontario ecosystem food web, secondary consumers are typically carnivores that eat primary consumers. You would identify these organisms in the provided diagrams by looking for entities colored in blue. Examples might include certain species of small fish or birds.

Explanation:

In a food web, secondary consumers are typically carnivores that eat the primary consumers, which are herbivores. An organism that fits this description in the Lake Ontario ecosystem would be classified as blue in the provided food web diagrams. Since specific organisms aren't listed in your question, you would need to look for organisms colored in blue in the figures you've mentioned (Figure 37.6 or Figure 46.6) for the correct secondary consumers in that ecosystem.

Secondary consumers play a crucial role in the ecosystem by controlling the population of primary consumers and are themselves a food source for tertiary consumers. Examples of secondary consumers might include small fish or certain bird species that feed on primary consumers such as zooplankton or insects. Remember, in some ecosystems, some organisms may have a mixed diet that can place them in multiple trophic levels depending on their food choice at the time.

True or false: male older adults are abused at a higher rate than are women.

Answers

The answer False. Male older adults are not abused at a higher rate than women.

Much gender-based violence or abuse is directed towards women. This term is treated on the war against women, but a war in gender violence is a man's issue.

Answer: The given statement is false.

Explanation:

Women are more prone to abuse as compared to men. This is because we are living in a stereotype society where till now women are considered weak, silent, and easy to harass.

Therefore, due to this women are abused emotionally, mentally and physically. Whereas men still feel that they have the right to do anything and they are powerful than women both physically and emotionally.

As still now head of the family is a male older adult to whom rest of the family members agree.

Hence, we can conclude that the statement male older adults are abused at a higher rate than are women, is false.

b. particles move from an area that is less concentrated to an area that is more concentrated.
c. particles move to different areas but always return to their starting point.
d. particles move slightly but stay in almost the same place?

Answers

The answer should be A, particles move from an area that is more concentrated to an area that is less concentrated.

The process of diffusion happens naturally, no extra energy is needed for this process. Think of a cup of water. If you put a drop of blue ink to the cup of water, you will see that at first the ink stays in a drop, then slowly spread out to the other parts of water until the whole cup of water is blue. This is the process of diffusion. The ink particles moves from a area of higher concentrated (the drop) to the area of lower concentration (the rest of the water). The net movement of diffusion happens until equilibrium, where both sides of the solution has a same concentration of solute (ie. The whole cup of water turns blue). At this time, the particles still move freely, but they don't have a net movement (the particles moving to the left side equals to the one moving to the right).

Note that diffusion applies to any fluid (liquid/gas), and the net movement must be down a concentration gradient.

During diffusion, particles move from an area that is more concentrated to an area that is less concentrated.

While a 31-year-old multigravida at 39 weeks' gestation in active labor is being admitted, her amniotic membranes rupture spontaneously. the client's cervix is 5 cm dilated, the presenting part is at 0 station, and the electronic fetal heart rate pattern is reassuring. what should the nurse do first?

Answers

The nurse should first note the amount, color as well as the odor of the amniotic fluid.

Explanation

When a patient’s membrane ruptures spontaneously, the nurse should start by checking the consistency, odor, as well as the volume of the amniotic fluid. For this case, there are minimal chances of cord prolapse because the fatal head is already engaged and at 0 station. If the fatal head is not yet engaged, the nurse should start by checking for cord prelapse if the membrane ruptures spontaneously.

Why is it more practical to prepare karyotypes by looking at somatic diploid cells rather than haploid gametes?

Answers

Because both sets of chromosomes, which are present in somatic diploid cells, need to be examined.

The haploid gametes only contain half of the chromosomes. That is why it is more practical to prepare karyotypes by looking at somatic diploid cells rather than haploid cells.

What is karyotyping?

It is a test for examining the chromosomes in a given sample of cells. This test is used for identifying the genetic problems that have resulted in a disorder or disease. Almost any tissue can be used for performing this test. These can include Amniotic fluid, Blood, Bone marrow, or even placenta.

The test is performed by placing the sample in a special dish or a tube. It is then allowed to grow in the laboratory. Then the cells are later taken from the new sample and are then stained.

A microscope is then used for to examine the size, shape, and number of chromosomes in the sample of cells. The sample that is stained is photographed for showing the arrangement of the chromosomes. This arrangement is called a karyotype.

This can be used for identifying certain problems through the number of chromosomes or the arrangement of the chromosomes. Thousands of genes are stored in DNA and the basic genetic material is present in the chromosome.

Therefore, the haploid gametes only contain half of the chromosomes. That is why it is more practical to prepare karyotypes by looking at somatic diploid cells rather than haploid cells.

When would a researcher be most likely to observe resource partitioning? between two allopatric populations that eat the same thing between two sympatric species that eat similar-sized seeds between two sympatric species, one herbivore and one carnivore between two species, one predator and one prey?

Answers

The answer is ‘two sympatric species that eat similar-sized seeds’. Sympatric speciations occur when a species population diverges without a physical barrier. Resources partitioning could occur when individuals in a population compete for same resources. Some individuals in that population may begin to utilize different resources to minimize the competition (and avoid being competitively excluded from the population).  Over time, this results in a divergence of the populations that utilize different resources hence carving out different niches.

Predict how an unusually prolonged drought might affect a biological community

Answers

Primary consumers (such as grazers and browsers) of the biological community will put pressure on the primary producers (these are plants) since the primary producers have limited resources (water) to reproduce due to the drought. The primary producers hence become scarce and cause the primary consumers to compete for limited resources. This causes the primary producers to reduce in population. Reduction in their population causes limited resources for secondary consumers and this cascades up the food web to tertiary consumers.

In cherry trees, white flowers are dominant over pink flowers. cross a homozygous dominant tree with a purebred recessive tree. what is the phenotypic ratio of the offspring?
a. 4 ww
b. 4 white selected:
c. 4 ww
d. 4 pink

Answers

All will be white (ww).

Final answer:

The offspring from crossing a homozygous dominant cherry tree with white flowers and a purebred recessive tree with pink flowers will all have white flowers. The phenotypic ratio is therefore all white flowers. (Option b)

Explanation:

When crossing a homozygous dominant cherry tree with white flowers (WW) with a purebred recessive cherry tree with pink flowers (ww), the phenotypic ratio of the offspring will be all white flowers. Since white flowers are dominant, all offspring will inherit one dominant allele (W) from the homozygous dominant tree and one recessive allele (w) from the purebred recessive tree, resulting in a genotype of Ww for each offspring. Therefore, each offspring will exhibit the white flower phenotype.

It's essential to note that while the phenotypic ratio is all white flowers, the genotypic ratio is 1:1 for heterozygous (Ww) and homozygous dominant (WW) individuals among the offspring. This illustrates the principle of dominance, where the presence of one dominant allele (W) leads to the expression of the dominant trait (white flowers) in the phenotype.

The correct answer to the question is b. 4 white.
