Why hydrophytes do not have cuticle on stem or leaves? answer just in 4 to 5 lines

Answers

B-Its hydrogen icon concentration is low
C-It is neutral
D-It can act as a buffer

Answers

Hey There!!~

Which of the following describes why ice floats?

Your answer is B. The density of ice is lower than that of liquid water. Because, As the water cools, the particles slow down and the bonds last longer. These bonds cause the water molecules within ice to form a lattice-like structure that is less dense than liquid water. So, ice floats on the more dense liquid water.

Why is water vital to maintaining a constant internal environment?

Your answer is C. It is good solvent. It is the maintenance of a constant internal despite changes in internal and external conditions. In the human body, this includes control of: blood glucose concentration.

Your answer is A. Its pH is below 7. Because, An acidic solution is one in which the concentration of hydronium ions is greater than that of hydroxide ions. This makes the pH less than 7. An acidic solution is an electrolyte and conducts electricity.

Hope This Helps!!

Answers

Zygospores

Zygomycota produce zygospores, which germinate into new hyphae.

Explanation;

The reproductive world of fungi ranges from bursting spores to fruiting bodies.

During asexual reproduction, some hyphae become spore-producing bodies called sporangia or conidia. The group of fungi known as Zygomycota develop sporangia within a sac. This sac then bursts to release the spores.

Once the spores land on a suitable habitat, they germinate a new hypha that grows into a mycelium.

Zygomycota, Ascomycota and Basidiomycota each reproduce sexually. The difference is the structure the spores form in. Basidiomycota form fruiting bodies called mushrooms or basidius; Ascomycota have sacs called ascus; and Zygomycota produce zygospore.

Answer:

the answer is Zygospores

Answers

Answer and Explanation:

El sistema endocrino esta compuesto por tejidos y glándulas que se encuentran en distintas partes del cuerpo y que cumplen funciones de control sobre distintos órganos. Se encarga de la síntesis y secreción de hormonas en función de las necesidades del organismo.  Las glándulas secretan hormonas a la sangre que actúan como mensajeros químico y que son transportadas hasta los tejidos destino, donde transmiten la señal adecuada de regulación celular. El hipotálamo y la hipófisis son dos glándulas que se ubican en la zona central-inferior y en la base del cerebro, respectivamente. El hipotálamo regula el funcionamiento de la hipófisis a través de secreción hormonal. Secreta hormonas en capilares que se dirigen hacia la hipófisis. La hipófisis, también conocida como glándula pituitaria, secreta hormonas que se dirigen a distintos tejidos del cuerpo. Tanto el hipotálamo como la hipófisis están regulados por el sistema nervioso, cuyas unidades funcionales y estructurales son las neuronas. Estas se encargan de enviar impulsos nerviosos en la comunicación inter-neuronal. Ambos sistemas mantienen estrechos sistemas de comunicación.

Use the picture to tell if it is accurate , precise , or both?

Answers

Answer:

Accurate - Yes

Precise - Yes

Explanation:

Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.

Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.

Note that, a measurement may be accurate but not precise or be precise but not accurate.

In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.

Therefore, the measurements are both precise and accurate.

b. __________ T-cells mature in the thymus before they circulate Immunological.
c. __________ B cells differentiate into plasmocytes.
d. __________ Antibodies attach to specific targets.
e. __________ B cells mature in red bone marrow before they circulate antigen.
f. ___________Memory T cells are activated later by the same 6 antigen.
g. ___________NK cells police peripheral tissues for abnormal and cancer cells.

1. Cell-mediated Immunity
2. Anti-body mediated immunity
3. Immunological surveillance

Answers

Answer:

to. 1. Cell-mediated immunity Cytotoxic T lymphocytes attack and destroy foreign cells and viruses Antibody-mediated immunity

b.1. Cell-mediated immunity T cells mature in the thymus before they circulate. Immune.

C. 1. Cell-mediated immunity B cells differentiate into plasma cells.

re. 2. Antibody-mediated immunity Antibodies adhere to specific targets.

me. 1. Cell-mediated immunity B cells mature in the red bone marrow before they circulate the antigen.

f.1. Cell-mediated immunity Memory T cells are subsequently activated by the same 6 antigens.

g.3. Immune surveillance NK cells monitor peripheral tissues for cancer and abnormal cells.

Explanation:

Cellular immunity is mediated by the cells of the immune defense, it presents different times, in the first time the PMN appear, in the second time the antigen presenting cells, and lastly the lymphocyte lineage.

Antigen presenting cells have the ability to phagocytose and express antigen on their surface to facilitate the formation of antibodies.

Surveillance immunity refers to the lymphocytes that are responsible for monitoring or controlling cell mutations or uncontrolled growth due to genetic mutations.

Neoplastic cells express histocompatibility complexes on their surface that make them recognized by these lymphocytes and this is how they are responsible for inducing self-destruction or phagocytosis of the neoplastic cell.

Humoral immunity refers to the chemical substances that function as mediators of cell activity, these are: pro and anti-inflammatory cytokines, complement chain, nitric and nitrous acid, oxygen free radicals, interleukins, growth factors and tumor necrotic factor alpha - beta
