Tameeka is at a point in her pregnancy during which the major organs and structures of her baby are first developing. which period of prenatal development is tameeka currently experiencing? fetal embryonic placental germinal umbilical

Answer:

The protists that probably would have originated from endosymbiosis were amoeba and paramecium. On the basis of the theory of endosymbiosis, it is possible that some of the non-photosynthetic species produced a symbiotic association with organisms that possessed the tendency to perform photosynthesis with the help of chloroplasts. These species than would have gained the tendency to perform photosynthesis because of the supplementation of chloroplasts into their cells, and thus led to the formation of eukaryotic species comprising chloroplasts.  

The answer is Bantu. They had already developed immunity to malaria due to exposure in their native environment. As they migrated southwards to conquer more land, they met the pygmies and the Khoisan. The Bantus had carried with them the malaria vectors. When the mosquitos infected the pygmies and the Khoisan populations, who had no immunity against malaria, the disease reduced their populations drastically hence enabling the Bantus to conquer their land.

Answer:

The answer is A. Phosphorus

Explanation:

Phosphorus isn't used in creating the fatty acids of early Earth's waters of the past because it is a poisonous, combustible nonmetal chemical (atomic number 15) and one of it's main uses is in the production of fertilizer.

The correct option is (A). Phosphorus is most likely not present in creating the fatty acids of early Earth's waters of the past.

A fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28.

Moreover, fatty acids are the building blocks of the fat in our bodies and in the food we eat. During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood. Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.

Therefore, fatty acids are energy sources and membrane constituents. They have biological activities that act to influence cell and tissue metabolism, function, and responsiveness to hormonal and other signals.

Explanation:

Final answer:

In a gel electrophoresis, the protein with a molecular weight of 10,000 Da would be found closer to the wells than the 75,000 Da protein because smaller proteins migrate faster through the gel.

Explanation:

When considering which protein would be found closer to the wells in a gel electrophoresis setup, we need to take into account the molecular weights of the two proteins in question. Generally, smaller proteins move faster through the gel matrix, due to lesser resistance encountered within the gel's pores. A protein with a molecular weight of 10,000 Daltons (Da) would exhibit faster migration compared to a larger protein with a molecular weight of 75,000 Da. Therefore, after running the gel electrophoresis, one would expect to find the 10,000 Da protein closer to the wells than the 75,000 Da protein because it is smaller and moves more quickly through the gel.

Answer: A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration.

In the process of photosynthesis the plants in the presence of sunlight, water and carbon dioxide produces a carbohydrates as food and oxygen is liberated into the atmosphere. The process of photosynthesis takes place in day and plants avail oxygen from the roots and leaves for respiration. The food produced is broken down into carbon dioxide and water with the release of energy in the presence of oxygen during cellular respiration. Plants produce oxygen as a byproduct of photosynthesis and use oxygen for cellular respiration.

On the basis of the above information, A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration is the correct statement that describes the relationship between plants and oxygen.

Final answer:

The correct statement is that plants produce oxygen during photosynthesis and require oxygen for cellular respiration. Plants use sunlight to convert CO2 and water into glucose and oxygen, and then use oxygen to convert glucose back into energy during respiration.

Explanation:

The statement that best describes the relationship between plants and oxygen is: plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration.

This is because during photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and release oxygen as a byproduct.

However, plants, like all other organisms, also need to break down this glucose to obtain energy, a process that occurs during cellular respiration and requires oxygen.

The given animals belongs to reptiles.

The class reptiles are cold blooded animals which means that the temperature of their body changes according to the surrounding temperature.

They mostly lay eggs and in some cases the eggs are hatched by the females inside the water.

Their body has scales or plates to protect themselves from the predators. They live on land an in water for sometime and respire using lungs.

Answer:

Reptiles

Explanation:

Reptiles are vertebrate animals that belong to the Animalia Kingdom, Filo Chordata and Reptilia Class. In evolutionary history, reptiles were the first vertebrate animals to conquer the terrestrial environment. Examples of reptiles are turtle, jabuti, tortoise, snake, snake, alligator, crocodile, chameleon, iguana and lizard.

Reptiles are cold-blooded and petilothermal animals, meaning they are unable to maintain their constant body temperature. Thus, they require the heat of the environment to regulate body temperature. They have pulmonary respiration and a thick hard skin with the presence of scales or plaques.

Most reptiles are oviparous. Only a few snakes and lizards are ovoviviparous. The egg has the following embryonic annexes: amnium, chorion, yolk sac and allantoid. Some species allow eggs to still hatch within the female. When puppies are born they resemble adults, as development is straightforward.

The answer is their offspring (the liger) is infertile. The male liger is usually sterile and cannot breed. This shows that the two are different species (different species cannot produce viable offsprings). However, the two species share a common ancestor since the female liger (though abnormally large) can still reproduce with the lion or tiger population.   

Ans.

Homeostasis can be defined as the state of constant, steady internal conditions maintained by living organisms. One way to maintain homeostasis by animals is by eliminating waste products from the cells.

By doing this, cells excrete harmful toxins to outside through its cell membrane. Cell organelles that help in digestion of waste material in cells are lysosomes.

Thus, the correct answer is option). 'by eliminating waste through the cell membrane.'

Answer:

The oil spill in the ocean affects the aquatic food chain adversely as due to oil spills the organisms that live in that part of the ocean start dying due to lack of oxygen.  

As the fishes and other organisms die the species diversity decreases which decrease the food available for each trophic level in a food chain. Therefore the aquatic food web will become shorter.

Oil spills also affect the food web on land that is located near the spill because these oil spills come to the land by tides and then the plants and grasses present on that land absorb the oil that damage these primary producers. So oil spills on the land produce unsuitable habitat for wildlife to flourish therefore it adversely affect the food web of land.

Most importantly Vitamin D also help in building up the bones. The Vitamin D is responsible for the absorption of calcium from food which can help in building up the bones.      

The presence of life around hydrothermal vents is significant and diverse despite the challenging conditions of high temperature, pressure, and lack of sunlight. Life at these vents is made possible by chemoautotrophic bacteria, which serve as a food source for a range of unique and adapted species.

The statement that there is absolutely no life surrounding hyrdrothermal vents in the ocean is false. Hydrothermal vents spew superheated water that is rich in minerals such as metal sulfide. This environment presents unique challenges, but it is home to a variety of specialized organisms. The extreme conditions of high temperature, toxicity, pressure, and lack of sunlight make photosynthesis impossible, yet life thrives here thanks to chemoautotrophic bacteria, which use the energy stored in chemicals to produce food.

These bacteria form the base of a food chain that supports diverse species such as red and white tubeworms, crabs, and vent mussels. The unique adaptations of these organisms allow them to live in an environment that would be deadly to most other life forms. Some of these creatures include tubeworms that were discovered in 1977, which cluster around vents despite the toxic minerals, high pressure, cold temperature, and complete darkness. Moreover, other vent species such as ghost fish and crabs with eyes on their backs contribute to the complexity of this ecosystem. The organisms living around hydrothermal vents are an example of how life can adapt to extreme conditions and find alternative methods to obtain energy, thus flourishing in what seems inhospitable to human standards.

Answer:Territory

Explanation:The territory is where many animals must fight off predators and claim.

Final answer:

A territory is an area occupied and defended by an organism or population, fundamental to population ecology and the study of how species interact with their environment and ensure access to resources.

Explanation:

A "territory" is an area occupied and defended by an organism or population. In biology, when discussing population ecology, the term population describes all individuals of a species that live within a specific area and interact with one another. Defending territory is a behavior noted among various species and is often linked with the availability of essential resources such as food, water, or shelter. For example, a species that's territorial will actively defend its living space to ensure it has enough sustenance for itself and its offspring, particularly if the resources are scarce. The extent of a territory can be influenced by both natural boundaries such as rivers and mountains, as well as artificial boundaries like roads or human-made structures.

The correct sequence of CPR (Cardiopulmonary Resuscitation) for an adult when two rescuers are present follows the following sequence:

Check for responsiveness: Shake the person and shout, "Are you okay?"

Call for help: Instruct the second rescuer to call emergency services (911) and retrieve an automated external defibrillator (AED) if available.

Open the airway: Tilt the person's head back and lift the chin to open the airway.

Check for breathing: Look, listen, and feel for signs of breathing for no more than 10 seconds. If the person is not breathing or only gasping, proceed with CPR.

Initiate chest compressions: Place the heel of one hand on the center of the person's chest, and place the other hand on top. Push hard and fast, aiming for a compression depth of at least 2 inches (5 centimeters). Compressions should be delivered at a rate of 100-120 compressions per minute.

Coordinate compressions and breaths: Coordinate with the second rescuer to ensure uninterrupted compressions while switching roles.

Give rescue breaths: After every 30 compressions, deliver two rescue breaths. Open the person's airway again by tilting the head and lifting the chin. Pinch the person's nose shut and cover their mouth with yours, forming a seal. Give a breath that makes the chest rise visibly. Each breath should last about 1 second.

Continue cycles of compressions and breaths: Maintain a compression-to-breath ratio of 30:2 (30 compressions followed by 2 breaths). Continue this cycle until help arrives, an AED becomes available, the person shows signs of life, or you are too exhausted to continue.

Neurons act as integrators through spatial and temporal summation of signals at synapses and facilitation at axo-axonic synapses. Synapses allow neurons to add or summate various inputs to produce a sizable outcome. This procedure involves neurotransmission processes like exocytosis, ligand-gated ion channels, and an electrical potential.

Neurons act as integrators through synapses that allow for the transmission of information, chiefly through spatial and temporal summation, and facilitation. Spatial summation refers to the integration of inputs (excitatory and inhibitory postsynaptic potentials) from many different sources. Contrastingly, temporal summation refers to the cumulative effect of repeated stimuli over a short period of time, which can lead to an action potential if the compound postsynaptic potentials reach the threshold level.

At an axo-axonic synapse, a synapse between the axon of one neuron and the axon of another, the process of facilitation occurs, which increases the likelihood of the downstream neuron to fire an action potential. This is due to the increase in the number of neurotransmitters released into the synaptic cleft.

In essence, synapses allow neurons to summate or add together various inputs to produce a sizable outcome. This vital neurotransmission process includes exocytosis, endocytosis, ligand-gated ion channels, postsynaptic potentials, and the electrical potential of the neuron.
