Answer:

The correct answer is - deuterostomes.

Explanation:

Duetorstomes eggs ,During embryonic development the zygote undergoes cleavage. Cleavage results is slitting into multiple cells where ease cell has the ability to develop into a complete embryo when isolated.

the molecules in those gases have very little kinetic energy to push molecules apart. Because of this, the attraction between the molecules pulls them together and condenses the gases into a liquid, just like the water in the first tank. ... When the nitrogen evaporates, the liquid left behind is mostly oxygen.

Answer:

Tanning beds are NOT safer than the sun.

Explanation:

Science tells us that there's no such thing as a safe tanning bed, tanning booth, or sun lamp. Just one indoor tanning session can increase the risk of developing skin cancer (melanoma by 20%, squamous cell carcinoma by 67%, and basal cell carcinoma by 29%).

It helps date the rock layer.

Graptolites are considered index fossils because they have a relatively short geological range and are found in specific time intervals. By discovering a graptolite fossil in a rock layer, scientists can use the known age of the graptolite to determine the approximate age of the rock layer.

Index fossils are valuable for relative dating and correlation of rock layers, as they provide a reference point for determining the relative ages of other fossils and rock formations.

Legal bottlenecks and lack of capital are the factors that are general barriers of entry of small businesses into market

A fundamental obstacle for small enterprises in townships is a lack of financial resources and restricted access to finance. Due to a lack of collected data, many companies may struggle to raise starting money, receive loans, or attract investors.

Small enterprises may find it difficult to navigate complex regulatory frameworks and adhere to legal obligations, especially if township-specific administrative procedures or licensing restrictions are present. For enterprises, administrative procedures and compliance fees can be very challenging.

Energy transfer in ecosystems occurs through food chains, starting with producers, moving to consumers, and ultimately to decomposers.

In ecosystems, energy transfer takes place through food chains and food webs. The process begins with producers, such as plants, which convert sunlight into usable energy through photosynthesis.

Next, primary consumers, such as herbivores, consume the plants and obtain the stored energy. Secondary consumers, such as carnivores, then consume the primary consumers to gain energy.

Tertiary consumers, like apex predators, eat secondary consumers. Throughout the food chain, energy is lost as heat, and only about 10% is transferred between each trophic level. Finally, decomposers break down dead organisms, returning nutrients to the soil and restarting the cycle.

The aspect of the human skeletal system that provides forensic anthropologists with the most information about the age of skeletons is the fact that specific bones that exhibit sex differences. Option D

Among the options provided, the aspect of the human skeletal system that provides forensic anthropologists with the most information about a skeleton's age is the fact that specific bones exhibit sex differences.

While the shape and size of eye orbits, bone position changes over time, and bone hardening with exposure can provide some information about age, determining sex differences through specific bone characteristics (such as pelvic bones, skull features, or long bone dimensions) is often more reliable and widely used in forensic anthropology to estimate the age of a skeleton.

Acid-fast bacteria or acid-fast bacilli can be defined as the group of bacteria that have the ability to resist their decolonization by the acids which are used during the staining process.

An infection that is caused due to an acid-fast organism indicates that the individual is suffering from Tuberculosis or other myobacterial diseases.

An acid-fast bacteria has many protective and invasive techniques which makes the infection difficult to treat, and thus, long-term course of antibiotics is needed for the treatment of such infections.

Explanation:

The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.

Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r.  The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:

                RR    x    rr

 F1         Rr    Rr    Rr    Rr  

phenotype ratio = all violet flower color

                 Rr    x    Rr

F2          RR    Rr    Rr    rr

phenotype ratio = 3/4 violet flower color and 1/4 red flower color

97 red flower offspring out of 400 is approximately 1/4.

Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things.

Water and minerals are transported and used in vascular plants through :

In vascular plants the root hairs in the root take up water and minerals from the soil and this water and mineral is transported to the shoot and leaves of the plants through a tissue known as Xylem.

The phloem transports the food made by the plants which is in the form of organic nutrients such as amino acids.
