There are 5 biological kingdoms: Animalia, plantae, fungi, monera, and protista.
Plantae groups plant cells characterized by chlorophyll.
Monera groups prokaryotic organisms such as bacteria.
Fungi groups eukaryotic cells such as yeasts
Protista groups unicellular eukaryotic organisms such as amoebae.
The animal kingdom groups multicellular eukaryotic organisms that can therefore form tissues.
Sponges are primitive animal organisms, so they do not have embryonic development like other known animal organisms. However, the cells that make up the sponge are grouped and interact performing different functions of vital importance as in tissue.
Because of how they are organized and how they function, we can see that the definition of sponge fits only with the definition of the animal kingdom.

What is the most logical explanation for why Alice saw bubbles forming in the leaves of the elodea?
In the experiment, Alice placed a sprig of Elodea in water with sodium bicarbonate as a source of carbon and then placed it under a strong light so it would photosynthesize.
Given that photosynthesis takes a carbon source, water, and light to produce glucose and oxygen, the most logical conclusion is that the bubbles are formed because the Elodea plant is releasing oxygen (option c).

2a. Which curve was generated using an enzyme taken from a bacteria that lives in hot springs at temperatures of 70OC or higher and explain why? b. The optimum temperature for enzyme 1 (curve 1) is approximately?c. Which curve was most likely generated from an analysis of an enzyme from a human stomach where conditions are strongly acidic and explain why?
In this case, we need to remember how we detect an optimum in enzyme activity. As the reaction accelerates and reaches the slope the optimum has been reached, when conditions keep changing after the optimum, the curve descends.
2a, here we have a thermophilous bacteria that lives at a high temperature so is natural that the optimum of an enzyme of this bacteria be at high temperatures as is the case of curve 3.
b. For this curve we have a slope around 30°C so this is the optimum temperature.
c. Here the curve is generated with a pH range, and the dynamics is the same that with temperature. The human stomach has a pH around 2, so the most likely slope that corresponds with human enzyme is curve 4.

Is a survey of the guests about their preference of food at a party an observational study or experimental study? If it is an experiment, what is the controlled factor?
An observational study means that the researchers observe the data without changing anything, while in an experimental study the researchers change something to observe the effects of what they changed.
A survey of the preferred food of the guest is not changing anything, just asking for preferences, so this is an observational study.
The greater the difference in pressure the stronger winds will be ….true or false
Answer:
True
Explanation:
Yes the statement is true since the air flows from higher pressure to lower pressure and the rate of flow is directly proportional to pressure difference.
So increase in pressure difference will cause increase in rate of flow of air which means the winds will ne stronger.

PatternsShow the conservation of atoms in chemical reactions Compare the atoms in sugar and the atoms in other carbon-based moleculesAnd the meal we are looking into is Rices fish broski and sweet potato
During a chemical reaction the total mass remains the same. This means that the mass of the consumed reactants equals the mass of the created products. The number of atoms also remains the same but the molecules change.
Many meals have in their composition starch, a molecule that is formed by glucose monomers. When the human body uses glucose it transformes this carbon based molecule into water, carbon dioxide and energy.
The chemical reaction of this process is the following:
[tex]C_6H_{12}O_6+6O_2\text{ }\rightarrow6CO_2+6H_2O\text{ + energy}[/tex]As we can see the number of each atom that conforms the reactants equal those of the products:
in total (both in the reactats and the products):
6 carbon atoms
12 hidrogen atoms
18 oxigen atoms
In this reaction glucose and carbon dioxide are both carbon based molecules

In your own words, explain how growing urbanization leads to deforestation
Growing urbanization can lead to deforestation mainly in two ways. When people move from rural areas to the cities they tend to consume in a higher rate, because the ways of living in cities are different from those in rural areas. For people to consume more and to attend their urban needs (which includes electricity, piped water, constructions, etc), there is a need to extract more materials from nature that will be used in the processes that will make those things available. The second major impact of urbanization on deforestation is that the cities need to grow, and they grow taking land from natural forests and such. So, deforestation occurs to give place to the constructions and infrastructure needed in urban cities.
If molecules of mRNA have the following nucleotide base sequences, what will be the sequence of amino acids in polypeptides synthesized by eukaryotic ribosomes? Remember, transcription starts with an AUG codon. 1. 5′–AUGGGGAUACGCUACCCC–3′ 2. 5′–CCGUACAUGCUAAUCCCU–3′ 3. 5′–CCGAUGUAACCUCGAUCC–3′ 4. 5′–AUGCGGUCAGCCCCGUGA–3′
The mRNA is used to synthesize polypeptides in a process called translation, and for that the mRNA is interpreted as a series of groups with three nucleotides each, called codons. So for each three letters, we have a codon. The codons transcribe the following amino acids: Alanine, Arginine, Asparagine, Aspartic acid, Cysteine, Glutamic acid, Glutamine, Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Proline, Serine, Threonine, Tryptophan, Tyrosine, Valine, Selenocysteine.
The codons are organized in a chart, as the one that follows:
As the translation starts with an AUG codon, we sometimes have to leave some trios behind. The answer would be as follows:
1. AUG - met | GGG - gly | AUA - ile | CGC - arg | UAC - tyr | CCC - pro
The sequence would be MET-GLY-ILE-ARG-TYR-PRO
2. We will start only after the AUG codon
AUG - met | CUA - leu | AUC - ile | CCU - pro
The sequence would be MET-LEU-ILE-PRO
3. Again, we start after the AUG codon, and if the stop codon shows up the translation stops
The sequence would be only AUG - met | UAA - stop
MET
4. AUG - met | CGG - arg | UCA - ser | GCC - ala | CCG - pro | UGA - stop
The sequence would be MET-ARG-SER-ALA-PRO
carrier proteins moving from low to high concentration requires the use of energy to ____ substances. This is called ___ transport and uses ____ _____ and ______, which is cell ____
Carrier proteins moving from low to high concentration requires the use of energy to transport substances. This is called active transport and uses transmembrane proteins, pumps and vesicles, which is cell membrane.
Active transport is the type of transport where molecules are transported using energy. This energy can be in the form of ATP or the energy released during co-transport. In active transport, the solute is transported against the concentration gradient, i.e., from lower to higher concentration.
Vesicles are the single membranous self-made structures. These are actually small spherical buds formed due to the pinching off of the cell membrane. They are actively involved in transport across various organelles of the cell.

what forms xylem and phloem
The vascular tissue of vascular plants is made up of various kinds of cells and components. The primary components of vascular tissue are the xylem and phloem.
Remember that the xylem transports water and dissolved mineral salts and the phloem transports sap made by cells and by photosynthesis.
Therefore, both the xylem and phloem form the vascular tissue of plants.
Now, the formation of the xylem and phloem is given by the vascular cambium. This vascular cambium produces xylem and phloem cells and originates from procambium that has not completely differentiated during the formation of primary xylem and primary phloem.
Now, Xylem can contain three types of elongated cells: tracheids, vascular elements or vessels (tracheae), and fibers. At maturity, when they perform transport functions, all these cells are dead.
Then, the cells of Xylem are:
- Tracheids.
- Tracheas or Vessels.
The phloem consists of two types of conducting cells: sieve tubes, which are the most characteristic elements, and annex cells.
The cells of Phloem are:
- Sieve cell and sieve tubes.
- Albumin cells.
- Companion cells
We can conclude that the correct answer is:
Answer:The elements that form Phloem are:
sieve elements, phloem fibers, and phloem parenchyma cells.
The elements that form Xylem are:
long tracheary elements, parenchyma, and fibers.
