which part of a plant protects and ensures the survival of fertilized eggs
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.

The intertidal zone is home to an abundance of aquatic organisms, like the barnacle, that can survive periods where they are not underwater. What type of tide would most likely decrease the abundance of aquatic organisms, and why?
Downwelling because it creates a cold environment that is not suitable for all aquatic organisms
Upwelling because it creates a cold environment that is not suitable for all aquatic organisms
Neap tide because it creates a small difference between high and low tides, so organisms are in stable environments
Spring tide because it creates a large difference between high and low tides, so the organisms are in extreme environments
Answer:
Spring tide because it creates a large difference between high and low tides, so the organisms are in extreme environments
The organisms are in extremely harsh habitats due to spring tide, which greatly increases the difference between high and low tides, hence option D is correct.
What is spring tide?Crabs, sea stars, snails, seaweed, and algae live in the intertidal zones of rocky shorelines. Attaching themselves to the rocks, barnacles, mussels, and kelps can thrive in this setting.
In order to prevent drying out at low tide, barnacles and mussels may also store seawater inside of their closed shells.
Aquatic life is exposed to the atmosphere for a long time during low tide, when the sun, moon, and earth are in alignment, spring tides occur right after every full and new moon.
Therefore, the daily habitat for species living in intertidal zones is altered by the pattern of low and high-tide organisms in extreme environments, hence option D is correct.

True or False: The genotype of a carrier female for hemophilia is XHXh.
A) TRUE
B) FALSE
The genotype of a carrier female for hemophilia is XHXh (Hh). Hemophilia is a X-linked recessive disorder. Thus, the given statement is true.
What is Hemophilia?Hemophilia is usually an inherited bleeding disorder in which blood does not clot properly. Hemophilia can lead to spontaneous bleeding as well as bleeding following injury or the surgery. Blood contains many proteins which are called clotting factors which can help to stop bleeding.
There are two main types of hemophilia are A and B, with a third, rarer form which is called hemophilia C. Each type is directly related to a specific factor namely, hemophilia A is a factor VIII deficiency, hemophilia B is a factor IX deficiency, and hemophilia C is a factor XI deficiency.

Final answer:
The genotype of a carrier female for hemophilia being XHXh is TRUE. Hemophilia is a sex-linked disorder and women with one healthy and one defective X chromosome (XHXh) are carriers, without necessarily showing symptoms.
Explanation:
The statement that the genotype of a carrier female for hemophilia is XHXh is TRUE. Hemophilia is a sex-linked recessive disorder, which means that the gene causing the disorder is located on the X chromosome. Males have one X and one Y chromosome (XY), so if they inherit the defective gene (Xh), they will exhibit symptoms of hemophilia as they do not have another X chromosome to mask the effect. Females have two X chromosomes (XX), and when a female has one defective gene (Xh) and one normal gene (XH), she becomes a carrier for the disease without necessarily exhibiting symptoms, since the healthy allele (XH) compensates for the defective one.
A carrier female inherits one X chromosome with the hemophilia allele from one parent, and one healthy X chromosome from the other parent. As a result, female carriers have the genotype XHXh.
What part of the eye is composed of tiny nerves that transfer light energy to nerve impulses?
A population of mice has moved in a new area where the rocks are very dark. Due to natural genetic variation, some of the mice are black while others are tan. The bird is a predator of the mice. Predict what will happen after a few generations and explain why. Be sure to include the following words in your response: adaptation, survive, reproduce.
Final answer:
Black mice that are better camouflaged against the dark rocks have a higher chance of surviving and reproducing, leading to an increase in their frequency in the population.
Explanation:
Natural selection is the process by which individuals with advantageous traits in a particular environment are more likely to survive and reproduce. In the case of the hypothetical population of mice in a new area with dark rocks, the mice that are better camouflaged, such as those that are black, would have a higher chance of surviving and reproducing. Over time, this would result in an increase in the frequency of black mice in the population.
This adaptation to the dark environment provides black mice with a better chance of avoiding predators, like birds, as they are harder to spot against the dark rocks. Therefore, as the generations pass, the proportion of black mice in the population is expected to increase, while the proportion of tan mice may decrease.

Marine scientists have collected data showing that oceans have become warmer in recent years. This increase in temperature would reflect an increase in thermal energy stored in the ocean. If true, would this validate or invalidate the Law of Conservation of Energy? Invalidate, because energy should not enter a closed system Invalidate, because the amount of energy should stay constant everywhere Validate, because the ocean is an open system that can gain and lose energy Validate, because the overall energy in the ocean does not change when thermal energy increases
Answer: Validate, because the ocean is an open system that can gain or lose energy.
Explanation: Since the ocean receives thermal energy from the sun, the temperatures of the waters can increase and fluctuate in different areas. When these waters reach land, this energy is transferred to the land, whether it be the sand in the beaches, rocks, etc.
Validate, as the ocean is an open system that is capable of gaining or losing energy.
How is thermal energy stored in the ocean?This energy is transmitted to the land when these waves reach it, whether it be the rocks, sand, or other land features like beaches, water contracts and gets denser as it cools.
Water moves up and down through the ocean layers and as currents across the ocean as a result of temperature and salinity's effects on its density.
Ocean surface waters are warmed by solar energy, surface water can be significantly warmer than deep water in tropical areas. The ocean can be desalinated and power can be generated using this temperature differential.
Therefore, validate that since the ocean absorbs thermal energy from the sun, various parts of the ocean may see an increase or decrease in water temperature.

In the kidney, the structures that filter the blood are the nephrons. The glomerulus filters your blood, and the tubule restores necessary chemicals to your blood while removing waste. This is how the nephrons function.
What is nephron ?Each kidney made up of a million nephrons, which are filtering cells. A filter termed the glomerulus and a tubule are both parts of a nephron. Nephrons are an important part of kidney.
The glomerulus filters your blood, and the tubule restores necessary chemicals to your blood while removing waste. This is how the nephrons function.
Each nephron has a glomerulus, which is where blood is filtered. The glomerulus is a network of capillaries encircled by the glomerular capsule, which resembles a cup.
Nephrons' main tasks include filtering the blood of all waste products, including solid wastes and excess water, as well as reabsorbing, secreting, and excreting a wide range of compounds.
