Answer: The female reproductive ovule is fertilized by the pollen and ovule resides in the ovary. So the ovary protects and ensures the survival of fertilized eggs.
Female flowering part consists of stigma which ends up in the style leading to the ovary. Male reproductive part consists of filament which holds the anthers that produce pollen. Fertilisation in flowering plants takes place inside the ovary of the flower which encloses the ovules. The fertilised ovule develops into a seed and ovary forms the fruit. Seed contains and stores the food and the embryo for forming a new plant.
The fertilized egg or embryo is protected from harsh environment and predations in an internal fertilisation.
While sampling marine plankton in a lab, a student encounters large numbers of fertilized eggs. the student rears some of the eggs in the laboratory for further study and finds that the blastopore becomes the mouth. the embryo develops into a trochophore larva and eventually has a true coelom. these eggs probably belonged to a(n)?

When are expert judges needed to determine the content validity of a test?
a. always
b. when the trait being measures is ill-defined
c. when the trait being measured is highly technical
d. all of the above?
The correct option 'd. all of the above'. Expert judges are needed to determine the content validity of a test when the trait being measured is ill-defined, highly technical, or in general to ensure accurate measurement.
Content validity is crucial to ensure that an assessment includes the content or tasks it is supposed to measure accurately. Therefore, expert judges are particularly needed when the trait being measured is ill-defined or highly technical. This means the correct answer is 'd. all of the above', which covers all scenarios where the expertise of judges is essential for validating the measurement.

what role do producers and consumers play in the carbon cycle
Answer:
Carbon cycle refers to the biogeochemical cycle by which carbon is exchanged between atmosphere, hydrosphere, geosphere, and biosphere.
Producers like plants use carbon dioxide present in the atmosphere and fix carbon into organic compounds.
Thus, producers fix carbon and make it available in usable forms for consumers.
Consumers use carbon in the form of organic compounds such as glucose and use it for cellular respiration. It releases carbon back into the atmosphere in the form of carbon dioxide.
Thus, consumers return carbon to the atmosphere.

In regions where prevailing winds blow from the oceans to the shore, which of these is most likely to occur?
Final answer:
Sea breezes occur along coastlines when prevailing winds blow from the oceans towards the shore, with cool air moving toward the shore from the ocean during the day and reversing at night.
Explanation:
Sea breezes occur along coastlines when prevailing winds blow from the oceans towards the shore. During the day, when the air temperature on land is greatest and the air temperature above the water is coldest, cool air moves toward the shore from the ocean. This is because water has a higher specific heat capacity than land, meaning it can absorb and store more heat energy. At night, the breezes are reversed, with cool air moving from the land toward the ocean, as the air temperature above the land drops.
In humans, a cleft chin is dominant and no-cleft is recessive. What will the generations look like? Assume that Mendel’s method of crossing two true breeding parents with opposite traits is followed. Check all that apply. The P generation, F1 generation, and F2 generation will have all cleft chins. The P generation, F1 generation, and F2 generation will have all no-cleft chins. The P generation and F1 generation will have all cleft chins. The F1 generation will have all cleft chins. The P generation and F2 generation will have all no-cleft chins. The P generation and F2 generation will have cleft chins and no-cleft chins. The P generation, F1 generation, and F2 generation will have cleft chins and no-cleft chins.
The phenotype or physical appearance of all the three generations will be: P and F2 generations will have cleft chins and no cleft chins, respectively and F1 will also have all the cleft chins.
What is the phenotype of different generations?In humans, a cleft chin is dominant and no-cleft is recessive. If we assume that Mendel’s method of crossing two true breeding parents with opposite traits is followed, the generations will look like: The P generation and F2 generation will have cleft chins and no-cleft chins.
The P generation and F1 generation will have all cleft chins. The F1 generation will have all cleft chins. The P generation, F1 generation, and F2 generation will have cleft chins and no-cleft chins. Hence, the correct options are: The P generation and F2 generation will have cleft chins and no-cleft chins.
The P generation and F1 generation will have all cleft chins. The F1 generation will have all cleft chins. The P generation, F1 generation, and F2 generation will have cleft chins and no-cleft chins.

The P generation will show either all cleft chins or all no-cleft chins depending on their genotype. The F1 generation resulting from a cross between true-breeding parents will all have cleft chins since they are all heterozygous Bb. The F2 generation will exhibit both cleft and no-cleft chins in a 3:1 ratio of dominant to recessive phenotypes.
In humans, a cleft chin is a dominant trait, while no-cleft is recessive. When two true breeding parents with opposite traits are crossed, according to Mendel's principles, the following can be expected:
1. The P generation will consist of homozygous individuals, one parent with the dominant trait (BB) and one with the recessive trait (bb). Therefore, all members of this generation will show their respective phenotype - either all cleft chins if BB or all no-cleft chins if bb.
2. The F1 generation will result from crossing two true breeding parents, one with BB and one with bb, producing offspring that are all heterozygous (Bb) and express the dominant trait. Hence, all members will have cleft chins.
3. The F2 generation results when the F1 generation (all Bb) self-crosses. The offspring ratios will show both phenotypes in a 3:1 ratio, with approximately 75% having cleft chins and 25% having no-cleft chins due to the expected genotypic ratio of 1 BB: 2 Bb: 1 bb in Mendelian inheritance.
Therefore, the correct statements are, "The P generation and F1 generation will have all cleft chins," and "The F1 generation will have all cleft chins," and "The P generation and F2 generation will have cleft chins and no-cleft chins."

A light microscope that makes the specimen appear light on a dark background is called a(n) _____. compound microscope electron microscope dark-field microscope
The right option is; dark-field microscope
A light microscope that makes the specimen appear light on a dark background is called a dark field microscope.
Dark field microscopes are light microscopes that are used in different ways to clearly view various specimens that are unstained, transparent, and hard to see using a light field unit. Dark field microscopes are very effective because they show the details of unstained and live samples. It is also very simple to use, and inexpensive to set up.
Answer:
The answer is Dark-field microscope.
Explanation:
Dark-field microscope is a microscope that uses a focused beam of very intense light in the form of a hollow cone concentrated on the sample, where the illuminated object disperses the light and thus becomes visible against the dark background behind it, making the transparent portions of the Specimen remain dark, while surfaces and particles look bright. This form of illumination is used to analyze transparent and unpigmented biological elements, invisible with normal illumination, without killing the specimen.

What is the ultimate measure of evolutionary success?
There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.
One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.
You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.
Type of reproduction takes place in archaebacteria and eubacteria
Answer:
Explanation:
Before knowing their reproduction process let's first understand what is Archaebacteria and Eubacteria.
Archaebacteria- are the oldest living anaerobic organisms on earth. They are unicelled prokaryotes and can live in extreme conditions like inside a volcano vent, hot springs and acidic/alkaline aquatic environment.
Reproduction- They reproduce by asexual reproduction process. Binary fission takes place where the genetic material is duplicated and then the cell wall pinches off from the center and thereof divides into two new daughter cells. They may also divide by fragmentation or budding.
Eubacteria- are the most common organisms found and are known as the true bacteria. They are of single celled prokaryotic origin and have no nucleus, They occur commonly in three shapes i.e. round, rod and spiral.
Reproduction- Mostly, they reproduce by binary fission, where the parent cell divides into two new daughter cells. But some may divide by a process called budding where an outgrowth takes place in the parent cell which gets separated later and the parent cell remains with the new cell formed.
The enzyme lactase breaks the sugar lactose into which compound(s)
The enzyme lactase breaks the sugar lactose into two simple sugars: glucose and galactose. These can be absorbed into the bloodstream and used for energy.
Explanation:The enzyme called lactase plays a vital role in the human digestive system. Specifically, this enzyme breaks down the sugar lactose, which is found in dairy products, into two simpler sugars: glucose and galactose. These simple sugars can then be easily absorbed into the bloodstream and used by the body for energy. For example, if you consume a glass of milk, the lactase enzyme in your small intestine will break the lactose present in the milk down into glucose and galactose.
